- alloc_language_binding: Use strong GC handle as well for references. Fixes #15138 - Set the native instance field of Godot.Object to IntPtr.Zero when it's freed. - Create weak handles without tracking resurrection (that was causing trouble). This means we have to call notification predelete before queueing a native Object for deletion, and use the MonoObject* passed by the finalizer because the weak GC handle target will return NULL at this point.
