1defc4595b LibWeb: Make LiveNodeList store a NonnullGCPtr<Node const> root
This allows us to improve the const-correctness in RadioNodeList, which
has been made possible as of: 5f0ccfb499 now that a GC-visit accepts a
const GC pointer.

bfd354492e LibWeb: Put most LibWeb GC objects in type-specific heap blocks
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.

This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.

I left a few types unconverted to this mechanism because I got tired of
doing this. :^)

708263790a LibWeb: Implement LiveNodeList::first_matching
This function returns the first element which matches both the filter
for the LiveNodeList collection itself, and a further filter that is
supplied as an argument to this function.

c2bf391f81 LibWeb: Don't mark LiveNodeList as final
This is to accommodate for adding the RadioNodeList interface which
returns a live list of elements.

72c9f56c66 LibJS: Make Heap::allocate<T>() infallible
Stop worrying about tiny OOMs. Work towards #20449.

While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.

8de7e49a56 LibWeb: Remove unecessary dependence on Window from DOM and WebIDL
These classes only needed Window to get at its realm. Pass a realm
directly to construct DOM and WebIDL classes.

This change importantly removes the guarantee that a Document will
always have a non-null Window object. Only Documents created by a
BrowsingContext will have a non-null Window object. Documents created by
for example, DocumentFragment, will not have a Window (soon).

This incremental commit leaves some workarounds in place to keep other
parts of the code building.

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.

8d6db36cbb LibWeb: Add support for NodeList
This introduces 3 classes: NodeList, StaticNodeList and LiveNodeList.
NodeList is the base of the static and live versions. Static is a
snapshot whereas live acts on the underlying data and thus inhibits
the same issues we have currently with HTMLCollection.

They were split into separate classes to not have them weirdly
mis-mashed together.

The create functions for static and live both return a NNRP to the base
class. This is to prevent having to do awkward casting at creation
and/or return, as the bindings expect to see the base NodeList only.
