Add pre-processor stage after_filter

Browse source 
* Move `_match_entry` and `post_extract` to `process_video_result`. It is also left in `process_info` for API compat
* `--list-...` options and `--force-write-archive` now obey filtering options
* Move `SponsorBlockPP` to `after_filter`. Closes https://github.com/yt-dlp/yt-dlp/issues/2536
* Reverts 4ec82a72bb since this commit addresses the issue it was solving

to their final locations), "after_video"
