Linus Groh e5753443ae LibJS: Consistently make prototype the last argument in Object ctors
This is so that we can reliably allocate them in a template function,
e.g. in ordinary_create_from_constructor():

    global_object.heap().allocate<T>(
        global_object, forward<Args>(args)..., *prototype);

The majority of objects already take the prototype as the last argument,
so I updated the ones that didn't.
