Editorial: allow hosts to create ordinary global objects

[Ms2ger]

There doesn't seem to be a reason for this hook to only allow exotic objects.

Background: the global inside a shadow realm should be ordinary, which causes an issue for the pedantic reader when we try to use this hook. I understand that Node.js also uses an ordinary object here.

For context: it is already legal to have an ordinary global object that aren't just Object.create(Object.prototype) + primordials. The way you can do it is by letting InitializeHostDefinedRealm create it as Object.create(Object.prototype), and then the hosts can add more properties to it or change its prototype. Hence, this is entirely editorial.

However, having to "add more properties to it" makes it annoying when the global object is created through WebIDL, because WebIDL only has utilities to create an object from a given interface and not to "upgrade" an object to a given interface.

(I am the pedantic reader mentioned above)
