[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.

Let's introduce a new method, interpolate_value(), which does not reference ClutterAnimation and uses a ClutterInterval to express the initial and final states.
