Move RenderNodeAnimator to android.graphics.animation package

A wrapper still exists at android.view.RenderNode animator
as it needs access to internals of the view that would violate
the package layering if moved into android.graphics.animation.

This CL also moves the Java and cpp files associated with creating
a native interpolator that can be run directly on the RenderThread.
