LibWeb: Remove uses of obsolete PlatformObject::global_object()

This API is a relic from the time when it was important for objects to
have easy access to the Window, and to know it was the global object.

We now have more spec-related concepts like relevant_global_object and
current_global_object to pull the Window out of thin air.
