LibWeb: Support interfaces with the [Global] extended attribute

Browse source 
These are treated differently as the interface members are placed on the
object itself, not its prototype.
As the object itself still needs to be hand-written code, and we can no
longer fully hide the gnarly generated code in the prototype object,
these now generate a 'mixin' class that is added to the actual object
through inheritance.
