LibJS: Pass Realm to GlobalObject::initialize_global_object()

Browse source 
Global object initialization is tightly coupled to realm creation, so
simply pass it to the function instead of relying on the non-standard
'associated realm' concept, which I'd like to remove later.

This works essentially the same way as regular Object::initialize() now.

Additionally this allows us to forward the realm to GlobalObject's
add_constructor() / initialize_constructor() helpers, so they set the
correct realm on the allocated constructor function object.
