This Pull Request fixes test [`assert-throws-same-realm.js`](eb44f67274/test/harness/assert-throws-same-realm.js).
It changes the following:
- Handles global variables through the global object, instead of the `context`.
- Adds an `active_function` field to the vm, which is used as the `NewTarget` when certain builtins aren't called with `new`.
- Adds a `realm_intrinsics` field to `Function`.
* - add trace to VSCode launch
- comment out pushUndefined and Return
- Move call frame to its own file
- heading for code blocks needed to be on its own line
- Show the difference between the VM starting up and a new Call frame being ran
* add back in return opCodes
* Update boa/src/vm/mod.rs

Nodes implement CodeGen which generates instructions onto a stack held in Context.
The VM will interpret the instructions from Context.
There are some issues:
- Only basic instructions are added, but I'm working off https://developer.mozilla.org/en-US/docs/Mozilla/Projects/SpiderMonkey/Internals/Bytecode for now it should be easy to add more in.
- The Stack is a Vec, this isn't ideal (we may be able to live with it for now) but the stack should really be a fixed sized array. This isn't possible because Value can't be copied in there as it holds Rc and Gc values. Can we have fixed-sized Values that hold a pointer? Something like the "stackvec" crate should help
- put all VM related code behind "vm" feature flag

* implement this
* remove construct/call from Object instead set func
* get_this_binding() was wrong, fixed
* BindingStatus is now properly set
* `this` now works on dynamic functions
* Migrates all builtins to use a single constructor/call fucntion to match the spec
* Ensure new object has an existing prototype
* create_function utility
* needing to clone before passing through
New parser!
Plus loads of tidy up in various places.
