events: Make MetaGestureTracker work with the action event delivery

ClutterActions now no longer receive their events via
clutter_actor_event(), instead they get special treatment by the stage
now. Make the MetaGestureTracker work with this and stop emitting events
directly to Clutter via clutter_actor_event(), but instead let them get
through to Clutter (but still not to Wayland).
