Basically extended the ValueAnimator to support a new type: pathType.
Add the PathDataEvaluator internally to interpolate path data.
Update test to show the path morphing.

The test case is showing that AnimatedVectorDrawable is able to use path to
define time interpolator and object movement now.

Currently as a hidden class.
It can support many the animations now as far as ObjectAnimator and
hierarchical group can support.
And we don't have path morphing yet.
Also support the Animator / Interpolator inflation from Context and Resources.
