Implement SkiaRecordingCanvas, RenderNodeDrawable, GLFunctorDrawable,
LayerDrawable, StartReorderBarrierDrawable, EndReorderBarrierDrawable.
Move AnimatedRoundRect and AnimatedCircle in a separate file.
All Skia pipeline files are moved in hwui/pipeline/skia folder.
Add unit tests for RenderNodeDrawable, StartReorderBarrierDrawable,
EndReorderBarrierDrawable and SkiaRecordingCanvas.

Test: I tested manually on 6P devices and did run the unit tests.
