Do not lock forwarding table during snapshot writing: This is a follow-up to [0], which made the [WeakTable] used during snapshot writing per isolate. Since each isolate has it's own table now, there's not reason to lock it during snapshot writing. Furthermore we speed up RawObject::InVMIsolateHeap() which was super slow due to locking "vm-isolate"'s page space and walking all pages.
