mpv: use yt-dlp instead of youtube-dl

youtube-dl has been abandoned and is now unusable to stream a
youtube.com video.

The mpv team decided to move on with the yt-dlp fork[1]. However, they
did not cut a new mpv release yet.

Backporting the relevant commit and updating the wrapper to expose
yt-dlp instead of youtube-dl.
