Add regex to --match-filter

Browse Source 
This does not fully deprecate `--match-title`/`--reject-title`
since `--match-filter` is only checked after the extraction is complete,
while `--match-title` can often be checked from the flat playlist.

Fixes: https://github.com/ytdl-org/youtube-dl/issues/9092, https://github.com/ytdl-org/youtube-dl/issues/23035
