StAdjustment implements the ClutterAnimatable interface, so we can already animate its properties with ClutterPropertyTransitions. But as it is currently not possible to associate a transition with an adjustment, it must be owned (and kept alive in case of GC) by the calling code. Change that by implementing the same (add|remove|get)_transition() API as ClutterActor, so we can use a familiar API and even duck typing in case of javascript. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/669
