VectorDrawable native rendering - Step 4 of MANY

This CL runs VectorDrawable animation on RenderThread. The changes in this CL
include:
- Convert all the animators in AnimatorSet for AVD into a set of RenderNodeAnimators.
- Hook up the new animators with RenderThread
- Add drawOp in RecordingCanvas for drawing VD so that during the animation
  on RenderThread, all the property changes on VD can be reflected on the screen.

TODO:
- Implement reverse and reset for AVD.
