6f433c8656 LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.

There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.

8cda70c892 LibWeb: Move event listeners, handlers and callbacks to the GC heap
This patch moves the following things to being GC-allocated:
- Bindings::CallbackType
- HTML::EventHandler
- DOM::IDLEventListener
- DOM::DOMEventListener
- DOM::NodeFilter

Note that we only use PlatformObject for things that might be exposed
to web content. Anything that is only used internally inherits directly
from JS::Cell instead, making them a bit more lightweight.

40a70461a0 LibWeb: Replace GlobalObject with Realm in wrapper functions
Similar to create() in LibJS, wrap() et al. are on a low enough level to
warrant passing a Realm directly instead of relying on the current realm
from the VM, as a wrapper may need to be allocated while no JS is being
executed.

c37820b898 Libraries: Use default constructors/destructors in LibWeb
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#cother-other-default-operation-rules

"The compiler is more likely to get the default semantics right and
you cannot implement these functions better than the compiler."

1422bd45eb LibWeb: Move Window from DOM directory & namespace to HTML
The Window object is part of the HTML spec. :^)

5aacec65ab LibWeb: Rewrite EventTarget to more closely match the spec
This isn't perfect (especially the global object situation in
activate_event_handler), but I believe it's in a much more complete
state now :^)

This fixes the issue of crashing in prepare_for_ordinary_call with the
`i < m_size` crash, as it now uses the IDL callback functions which
requires the Environment Settings Object. The environment settings
object for the callback is fetched at the time the callback is created,
for example, WrapperGenerator gets the incumbent settings object for
the callback at the time of wrapping. This allows us to remove passing
in ScriptExecutionContext into EventTarget's constructor.

With this, we can now drop ScriptExecutionContext.

0ee457dfdf LibWeb: Provide a default DOM::EventTarget::dispatch_event()
All EventTarget subclasses except Window do the same exact thing in
their overrides, so let's just share an implementation in the base.

1d8f8ea5b1 LibWeb: Add initial support for AbortController and AbortSignal
The DOM specification says that the primary use case for these is to
give Promises abort semantics. It is also a prerequisite for Fetch,
as it is used to make Fetch abortable.
