It was reported that the `dbg!` output of native errors was too long. This PR skips printing the `Realm` of a `JsNativeError`. It also improves the `dbg!` output of `Realm` by skipping printing `Inner` and only printing the inner fields of `Inner`.
Noticed we were using this pattern on a couple of places, so I abstracted it behind a `ContextCleanupGuard` struct.
Let me know if you remember another place where this pattern would apply.

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`
We have currently some bugs related to binding assignments on arithmetic operations (`+=`, `++`, `?=`, etc.), but fixing those was getting a bit complex with our current bindings APIs.
This PR refactors our binding handling APIs to be a bit easier to use.
Most of the time that we have a `ByValue` ( `[ value ]` syntax ) it is for arrays and the value is usually an index. This PR adds a fast path to the instructions (without calling `.borrow()` on the object to check if its an array)
For example, this code:
```js
let a = [1, 2, 3]
for (let i = 0 ; i < 10000000; ++i) {
a[i % 3] += a[ (i + 1) % 3 ]
}
```
Using `hyperfine`, it ran `1.38` times faster on this PR.
```bash
Benchmark 1: ./boa_main test.js
Time (mean ± σ): 16.504 s ± 0.192 s [User: 16.440 s, System: 0.020 s]
Range (min … max): 16.328 s … 16.938 s 10 runs
Benchmark 2: ./boa_direct_array_access test.js
Time (mean ± σ): 11.982 s ± 0.038 s [User: 11.939 s, System: 0.013 s]
Range (min … max): 11.914 s … 12.035 s 10 runs
Summary
'./boa_direct_array_access test.js' ran
1.38 ± 0.02 times faster than './boa_main test.js'

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.
This Pull Request fixes/closes #2717 and related to #2479
This was caused by an incorrect to digit conversion.
Here are two examples that always cause a panic. They have been added as a test in `number/test.rs`
```js
(0.1600057092765239).toString(36)
(0.23046743672210102).toString(36)
```
Part of ES5.
This PR allows `Date` objects to store an invalid `NativeDateTime` as a `i64` and check when `getMinutes` (or other methods) call and check if it's valid, like in the spec
This was failing some `Date` tests, when calling `new Date(8.64e15)` then calling `getTime()` it was returning `NaN` when it should return the passed value `8640000000000000` (as node does)
