[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)
