Implement `Hidden classes` (#2723)
This PR implements `Hidden Classes`, I named them as `Shapes` (like Spidermonkey does), calling them maps like v8 seems confusing because there already is a JS builtin, likewise with `Hidden classes` since there are already classes in JS.
There are two types of shapes: `shared` shapes that create the transition tree, and are shared between objects, this is mainly intended for user defined objects this makes more sense because shapes can create transitions trees, doing that for the builtins seems wasteful (unless users wanted to creating an object with the same property names and the same property attributes in the same order... which seems unlikely). That's why I added `unique` shapes, only one object has it. This is similar to previous solution, but this architecture enables us to use inline caching.
There will probably be a performance hit until we implement inline caching.
There still a lot of work that needs to be done, on this:
- [x] Move Property Attributes to shape
- [x] Move Prototype to shape
- [x] ~~Move extensible flag to shape~~, On further evaluation this doesn't give any benefit (at least right now), since it isn't used by inline caching also adding one more transition.
- [x] Implement delete for unique shapes.
- [x] If the chain is too long we should probably convert it into a `unique` shape
- [x] Figure out threshold ~~(maybe more that 256 properties ?)~~ curently set to an arbitrary number (`1024`)
- [x] Implement shared property table between shared shapes
- [x] Add code Document
- [x] Varying size storage for properties (get+set = 2, data = 1)
- [x] Add shapes to more object:
- [x] ordinary object
- [x] Arrays
- [x] Functions
- [x] Other builtins
- [x] Add `shapes.md` doc explaining shapes in depth with mermaid diagrams :)
- [x] Add `$boa.shape` module
- [x] `$boa.shape.id(o)`
- [x] `$boa.shape.type(o)`
- [x] `$boa.shape.same(o1, o2)`
- [x] add doc to `boa_object.md`

Added a Boa runtime (#2743)
This Pull Request fixes/closes #718. It changes the following: - Adds a new `boa_runtime` crate, that will only include `console` for now - Changes the `boa_cli` crate to use the new `boa_runtime` crate for the console, instead of the `console` feature of `boa_engine` - Removes the `console` feature in `boa_engine` - Adds a new `boa_testing` helper crate with some useful functions for testing `boa`. This part duplicates the code from `boa_engine`, but I could not make `boa_engine` work with this crate as a dependency due to circular dependencies. Maybe doing it a bit generic could work, but didn't have enough time to check it. To be checked: wether the WASM example works as expected with the console. |

Bump regex from 1.7.3 to 1.8.0 (#2855)
Bumps [regex](https://github.com/rust-lang/regex) from 1.7.3 to 1.8.0. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/rust-lang/regex/blob/master/CHANGELOG.md">regex's changelog</a>.</em></p> <blockquote> <h1>1.8.0 (2023-04-20)</h1> <p>This is a sizeable release that will be soon followed by another sizeable release. Both of them will combined close over 40 existing issues and PRs.</p> <p>This first release, despite its size, essentially represent preparatory work for the second release, which will be even bigger. Namely, this release:</p> <ul> <li>Increases the MSRV to Rust 1.60.0, which was released about 1 year ago.</li> <li>Upgrades its dependency on <code>aho-corasick</code> to the recently release 1.0 version.</li> <li>Upgrades its dependency on <code>regex-syntax</code> to the simultaneously released <code>0.7</code> version. The changes to <code>regex-syntax</code> principally revolve around a rewrite of its literal extraction code and a number of simplifications and optimizations to its high-level intermediate representation (HIR).</li> </ul> <p>The second release, which will follow ~shortly after the release above, will contain a soup-to-nuts rewrite of every regex engine. This will be done by bringing <a href="https://github.com/BurntSushi/regex-automata"><code>regex-automata</code></a> into this repository, and then changing the <code>regex</code> crate to be nothing but an API shim layer on top of <code>regex-automata</code>'s API.</p> <p>These tandem releases are the culmination of about 3 years of on-and-off work that <a href="https://redirect.github.com/rust-lang/regex/issues/656">began in earnest in March 2020</a>.</p> <p>Because of the scale of changes involved in these releases, I would love to hear about your experience.

More specifically, any ASCII character except for <code>[0-9A-Za-z<>]</code> can now be escaped. Also, a new routine, <code>is_escapeable_character</code>, has been added to <code>regex-syntax</code> to query whether a character is escapeable or not.</li> <li>[FEATURE <a href="https://redirect.github.com/rust-lang/regex/issues/547">#547</a>](<a href="https://redirect.github.com/rust-lang/regex/issues/547">rust-lang/regex#547</a>): Add <code>Regex::captures_at</code>.

Implement async functions using generators (#2821)
This should hopefully fix more async/futures issues related to resuming execution in the future, since we can leverage generator logic to handle this for us. It changes the following: - Refactors `GeneratorContext` to handle context preparation. - Reuses the functionality of `GeneratorContext` in `Await`. - Removes `EarlyReturnType` in favour of a single `r#await` bool flag in `CallFrame`. |

Allow passing owned `HostHooks` and `JobQueues` to `Context` (#2811)
This allows `thread_local` contexts to have owned `HostHooks` and `JobQueues`. It changes the following: - Creates a new `MaybeShared` struct that can hold either a reference or an `Rc`. - Changes the `job_queue` and `host_hooks` parameters of `Context` to use `MaybeShared`. This PR also allows us to make `SimpleJobQueue` the default promise runner, which I think it's pretty cool :) cc @lastmjs |

Implement debug object for CLI (#2772)
Currently some debugging stuff in JavaScript land is difficult to impossible, like triggering a GC collect, this is not impossible to do in JavaScript the way I triggered it was by creating a huge amount of object `for (let i = 0; i < 100000; ++i) { ({}) }` but this is cumbersome and not guaranteed to trigger a gc.
This PR implements `--debug-object` flag that injects the `$boa` debug object in the context, the object is separated into modules currently `gc`, `function`, `object`.
We can now do `$boa.gc.collect()`, which force triggers a GC collect.
Or sometimes I wanted a trace (the current solution is great, you can trace stuff like `>>> 1 + 1` but that is also it's limitation), it traces everything, I sometimes have a scenario and just want to trace a single function in that scenario, that's why I added the `$boa.function.trace(func, this, ...args)` It only traces the function.
```js
>> $boa.function.trace((a, b) => a + b, undefined, 1, 2)
-------------------------Compiled Output: ''--------------------------
Location Count Opcode Operands
000000 0000 DefInitArg 0000: 'a'
000005 0001 DefInitArg 0001: 'b'
000010 0002 RestParameterPop
000011 0003 GetName 0000: 'a'
000016 0004 GetName 0001: 'b'
000021 0005 Add
000022 0006 Return
000023 0007 PushUndefined
000024 0008 Return
... (cut for brevity) ...
```
It also implements `$boa.function.flowgraph(func, options)`:
```js
$boa.function.flowgraph(func, 'graphviz')
$boa.function.flowgraph(func, { format: 'mermaid', direction: 'TopBottom' })
```
Printing the object pointer:
```js
$boa.object.id({}) // '0x566464F33'
```
It currently implements some functionality which we can grow it with our debugging needs since we are not restricted by a spec we can add whatever we want :)
I was originally going to implement this in #2723 (but the PR is too big), for shapes having functions like:
```js
$boa.shape.type({}) // Shared shape
$boa.shape.id({}) // 0x8578FG355 (objects, shape pointer)
$boa.shape.flowgraph({}) // printing the shape transition chain, like $boa.function.flowgraph
```
Shapes chains are very hard to debug once they are big... so having this type of debugging capability would make it much easier.

Implement `escape` and `unescape` (#2768)
<!--- Thank you for contributing to Boa! Please fill out the template below, and remove or add any information as you feel necessary. ---> This Pull Request implements the [`escape`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/escape) and [`unescape`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/unescape) functions. Both are technically deprecated, but they're also part of the [Additional ECMAScript Features for Web Browsers](https://tc39.es/ecma262/#sec-additional-ecmascript-features-for-web-browsers) section, so it is preferable to have them in place. |

For example: ```js let x = ((1 + 2 + -4) * 8) << 4 ``` Generates the following instruction(s) (`cargo run -- -t`): ``` 000000 0000 PushOne 000001 0001 PushInt8 2 000003 0002 Add 000004 0003 PushInt8 4 000006 0004 Neg 000007 0005 Add 000008 0006 PushInt8 8 000010 0007 Mul 000011 0008 PushInt8 4 000013 0009 ShiftLeft 000014 0010 DefInitLet 0000: 'x' ``` With constant folding it generates the following instruction(s) (`cargo run -- -t -O`): ``` 000000 0000 PushInt8 -128 000002 0001 DefInitLet 0000: 'x' ``` It changes the following: - Implement ~~WIP~~ constant folding optimization, ~~only works with integers for now~~ - Add `--optimize, -O` flag to boa_cli - Add `--optimizer-statistics` flag to boa_cli for optimizer statistics - Add `--optimize, -O` flag to boa_tester After I finish with this, will try to implement other optimizations :) [cfo]: https://en.wikipedia.org/wiki/Constant_folding |

API to construct a `NativeFunction` from a native async function (#2542)
~~Builds off of #2529.~~ Merged. This Pull Request allows passing any function returning `impl Future<Output = JsResult<JsValue>>` to the `NativeFunction` constructor, allowing native concurrency hooks into the engine. It changes the following: - Adds a `NativeFunction::from_async_fn` function. - Adds a new `JobQueue::enqueue_future_job` method. - Adds an example usage on `boa_examples`. |

Module parsing (#2411)
I'm creating this draft PR, since I wanted to have some early feedback, and because I though I would have time to finish it last week, but I got caught up with other stuff. Feel free to contribute :) The main thing here is that I have divided `eval()`, `parse()` and similar functions so that they can decide if they are parsing scripts or modules. Let me know your thoughts. Then, I was checking the import & export parsing, and I noticed we are using `TokenKind::Identifier` for `IdentifierName`, so I changed that name. An `Identifier` is an `IdentifierName` that isn't a `ReservedWord`. This means we should probably also adapt all `IdentifierReference`, `BindingIdentifier` and so on parsing. I already created an `Identifier` parser. Something interesting there is that `await` is not a valid `Identifier` if the goal symbol is `Module`, as you can see in the [spec](https://tc39.es/ecma262/#prod-LabelIdentifier), but currently we don't have that information in the `InputElement` enumeration, we only have `Div`, `RegExp` and `TemplateTail`. How could we approach this? Co-authored-by: jedel1043 <jedel0124@gmail.com> |

Cleanup intrinsics and move to realm (#2555)
Small (ish?) step towards having proper realm records This PR changes the following: - Moves `Intrinsics` to `Realm`. - Cleans up the initialization logic of our intrinsics to not depend on `Context`, unblocking things like #2314. - Adds hooks to initialize the global object and the global this per the corresponding [`InitializeHostDefinedRealm ( )`](https://tc39.es/ecma262/#sec-initializehostdefinedrealm) hook. Though, this is currently broken because the vm uses `GlobalPropertyMap` instead of the `JsObject` API to initialize global properties. |

Create `Source` to abstract JS code sources (#2579)
Slightly related to #2411 since we need an API to pass module files, but more useful for #1760, #1313 and other error reporting issues. It changes the following: - Introduces a new `Source` API to store the path of a provided file or `None` if the source is a plain string. - Improves the display of `boa_tester` to show the path of the tests being run. This also enables hyperlinks to directly jump to the tested file from the VS terminal. - Adjusts the repo to this change. Hopefully, this will improve our error display in the future. |
