applemedia: Add ProRes support to vtenc and vtdec
For vtdec, we continue to prefer NV12; else we pick whatever downstream wants. In the special case where we're decoding 10-bit or 12-bit ProRes formats, we will prefer AYUV64. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1214>
