Shannon Booth 637fd51595 LibWeb: Unify WebIDL C++ type generation
Represent WebIDL C++ types with a single CppType model that tracks
nullability, optional presence, and contained storage.

GC-like values now use GC::Ref/GC::Ptr directly, while containers choose
"plain", "Root", or "Conservative" container types depending on what
they contain. For example, sequence<Element> becomes a RootVector of
GC::Ref values, while sequence<SomeDictionary> becomes a
ConservativeVector only when the dictionary contains GC-like values.
This moves the generated bindings away from wrapping GC values in
GC::Root by default.

This has broad fallout as the types passed to interfaces for GC
objects changes almost fully across the board.
