No functional changes - we can still very easily get to the global object via `Realm::global_object()`. This is in preparation of moving the intrinsics to the realm and no longer having to pass a global object when allocating any object. In a few (now, and many more in subsequent commits) places we get a realm using `GlobalObject::associated_realm()`, this is intended to be temporary. For example, create() functions will later receive the same treatment and are passed a realm instead of a global object.
