[animation] Add ClutterAnimatable The ClutterAnimatable interface is meant to be used by GObject classes to override the value computation for an animatable property within the boundaries of an interval. It is composed of a single virtual function, animate_property(); its implementation will receive the ClutterAnimation used to animate the object; the property name; the initial and final interval values; and the progress factor as retrieved by the Alpha object bound to the Animation instance.

Deprecate ClutterAnimation, as well as clutter_actor_animate() ClutterPropertyTransition, and the implicit animation API based on ClutterTransition and ClutterAnimatable, are enough to replace this whole API.

animatable: Deprecate and replace animate_property() The animate_property() method of the Animatable interface is far less than optimal: • it has a direct reference to ClutterAnimation; • it has an interval decomposed as two values. These issues tie the Animatable interface with the Animation object, even though it's neither necessary nor future-proof. Let's introduce a new method, interpolate_value(), which does not reference ClutterAnimation and uses a ClutterInterval to express the initial and final states.
