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.
