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.
