LibJS: Rework how native functions are called to improve |this| value

Browse source 
Native functions now only get the Interpreter& as an argument. They can
then extract |this| along with any indexed arguments it wants from it.

This forces functions that want |this| to actually deal with calling
interpreter.this_value().to_object(), and dealing with the possibility
of a non-object |this|.

This is still not great but let's keep massaging it forward.
