display: Implement gesture-induced touch cancellation for wayland

Browse Source 
On wayland, touches are initially both handled by the compositor and sent
to clients, proceeding to cancellation on clients only after the compositor
claims the sequence for itself. Implement the cancellation detail through
MetaGestureTracker::state-changed.
