VideoCaptureManager: registering UMA no-frames-produced-by-source as Media.VideoCapture.Event

This is a tentative CL to consolidate the counting of video
capture sources that produce no frames (muted). ATM these are
wrongly counted, and IMHO they are more relevant when compared
to the amount of capture sessions that went right and/or
failed to start.
