[utils] Align traverse_obj() with yt-dlp

Thanks Grub4k for these:
* traverse `Iterable`s, from https://github.com/yt-dlp/yt-dlp/pull/6902, etc
* traverse `set` key for transformations/filters, `re.Match` group names, from
  https://github.com/yt-dlp/yt-dlp/commit/776995bc109c5cd1aa56b684fada2ce718a386ec, etc
* traverse `re.Match`es, from https://github.com/yt-dlp/yt-dlp/pull/5174
* always return list when branching, from https://github.com/yt-dlp/yt-dlp/pull/5170
