Implement HW Bitmap for Skia pipeline

Implement HW Bitmap for Skia pipeline. Use new Skia
SkImage::MakeFromAHardwareBuffer API, which will enable to
record HW Bitmap into a picture. Move logic that uploads
SkBitmap into a GraphicBuffer into pipeline specific classes.

Test: All CTS and other tests pass for HWUI pipleine. For Skia
pipeline graphics CTS tests pass, 2 UIRendering CTS tests which
excise HW bitmaps with color spaces fail, bitmapShaderEglImage
macrobench fails (to be fixed by a CL in Skia), HWUI unit tests
pass, no EGL leaks found.
