media: v4l2-controls: Add control for background detection
Add a generic V4L2 boolean control V4L2_CID_MPEG_VIDEO_BACKGROUND_DETECTION
that allows encoders to detect background regions in a frame and use fewer
bits or skip mode to encode them, potentially reducing bitrate for streams
with stationary scenes.
