LibWeb: Remove the internal window object from WebEngineCustomData

Browse source 
Now that no one needs a Window just to create prototypes, we can remove
the internal window Object from the main thread VM and get rid of the
HTML::Window include for it.

This finally solves the reference binding to nullptr error in ladybird
that shows up when compiling it with ASAN.
