Use libyuv for webcam video streams.
This patch significantly reduces YUV -> RGB conversion time in
SkCanvasVideoRenderer on ARM devices, by using the ARM optimized libyuv
library whenever possible. The speed improvement is significant, from 25ms
to 12ms per 720p frame on an ARM device.
As a result, the Camera app's frame rate increased from 19 FPS to 25 FPS.
TEST=Tested manually on both ARM and Intel devices.
BUG=347422
