[M120 Migration][MM] Camera and WebRTC patches migration.

This commit includes commits below.

- Add MJPEG support
Add support for MJPEG camera stream, jpeg frames are internally sent
with PIXEL_FORMAT_ENCODED instead of PIXEL_FORMAT_MJPEG, which avoids
the decoding in default camera pipeline and helps redirecting frames
towards the esplusplayer.
