This is the last sample format that was only in mpv and not in FFmpeg (except the spdif special formats). It was a huge pain, even if the removed code in af_lavrresample is pretty small after all. Note that this drops S24 from the ao_coreaudio AOs too. I'm not sure about the impact, but I expect it doesn't matter. af_fmt_change_bytes() was unused as well, so remove that too.
