With VIDEO_DAMAGE, the video uclass tracks updated regions of the frame
buffer in order to avoid unnecessary work during a video sync. Enable
the config in sandbox and add a test for it, by printing strings at a
few locations and checking the tracked region.

and reset the damaged region.

- Add patch "video: test: Test video damage tracking via vidconsole"
