options: also accept ffmpeg pixel format names

Browse Source 
Options that take pixel format names now also accept ffmpeg names.
mpv internal names are preferred. We leave this undocumented
intentionally, and may be removed once libswscale stops printing
ffmpeg pixel format names to the terminal (or if we stop passing the
SWS_PRINT_INFO flag to it, which makes it print these).

(We insist on keeping the mpv specific names instead of dropping them
in favor of ffmpeg's name due to NIH, and also because ffmpeg always
appends the endian suffixes "le" and "be".)
