libavfilter: Use type-safe format negotiation functions with enum parameters
...
Replace generic format functions with type-safe variants to prevent undefined
behavior with -fshort-enums compiler flag.
- ff_set_common_formats_from_list2 -> ff_set_*_formats_from_list2 (sample/pixel)
- ff_set_common_formats_from_list -> ff_set_*_formats_from_list (sample/pixel)
- ff_make_format_list -> ff_make_*_format_list (sample/pixel)
This adapts the upstream FFmpeg master patch to ffmpeg7 version.
