The intent is to use these to autogenerate prototype declarations for
Window and WorkerGlobalScope classes.
And the spec links are just nice to have :^)
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.
Specifically HTMLIFrameElement and HTMLObjectElement. HTMLEmbedElement
will gain it automatically once it's also converted to inherit from
BrowsingContextContainer.
There are a long list of conditions under which the HTMLObjectElement is
to queue an element task to load / determine an object's representation.
This handles the case where the data attribute has changed.
Much of the spec for determining the object's representation is not
implemented here. Namely, anything to do with XML documents or browser
plugins are left as FIXMEs.
