clutter/actor: Inherit clone branch depth from parent

Browse Source 
Children added to a parent after that parent (or its ancestors)
have already been cloned now inherit the clone branch depth of
the parent. Otherwise `clutter_actor_is_in_clone_paint` on the child
could return FALSE when it should have been returning TRUE.
