rawdec: refactor private option for raw video demuxers

Browse Source 
pixel_format/video_size only apply to 'rawvideo' (==uncompressed) demuxer
and make no sense for the other raw (== containerless) demuxers. Keep
only the framerate option for those.

Also use unique classes for all raw video demuxers
