[common:jwplayer] Improve jwplayer extraction and parsing (#31000)
* don't crash parser if jwplayer_data is invalid (empty, or no formats) * use `label` in `sources[n]` as `format_id` * relax `jwplayer().setup(...)` RE (also rework PR #27274 enhancement) * detect more manifest formats in _parse_jwplayer_formats() (from PR #29596) * improve metadata extraction (from PR #25433) * remember URLs in a set * use parse_resolution() in format * extract filesize in format (from yt-dlp) Co-authored-by: kikuyan <kikuyan@users.noreply.github.com> Co-authored-by: martin54 <martin54@users.noreply.github.com>
