Add support for generation of 10/12/14/16 bit bayer test pattern. The implementation is rather simplistic, just take the ARGB input, generate 16-bit data out of it instead of 8-bit, shift them as required by the output bitness, and apply endian swap. Example usage: ``` $ gst-launch-1.0 videotestsrc ! \ video/x-bayer,width=512,height=512,format=bggr12le ! \ bayer2rgb ! \ video/x-raw,format=RGBA64_LE ! \ videoconvert ! \ autovideosink ``` Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4686>
