Various subclasses of ClutterActorMeta need to reacto to being disabled. Right now, however, the only way to do that is by overriding GObject's 'notify' vfunc, and doing a string comparison against "enabled". Add a new vfunc to ClutterActorMeta in order to replace this bad practice. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1187
