media: uapi: add MEDIA_BUS_FMT_METADATA_FIXED media bus format.
MEDIA_BUS_FMT_METADATA_FIXED should be used when the same driver handles both sides of the link and the bus format is a fixed metadata format that is not configurable from userspace. The width and height will be set to 0 for this format.
