LibJS+LibWeb: Let Realm store a plain Object for [[GlobalObject]]

Browse source 
This removes the requirement of having a global object that actually
inherits from JS::GlobalObject, which is now a perfectly valid scenario.

With the upcoming removal of wrapper objects in LibWeb, the HTML::Window
object will inherit from DOM::EventTarget, which means it cannot also
inherit from JS::GlobalObject.
