gesture: Simplify gesture/widget interaction public API
The propagation phase property/methods in GtkEventController are gone, This is now set directly on the GtkWidget add/remove controller API, which has been made private. The only public bit now are the new functions gtk_gesture_attach() and gtk_gesture_detach() that will use the private API underneath. All callers have been updated.
