Disable PIP/background playback toggle

[nin0-dev]

"Disable PIP" would just let the video continue in background, audio-only.

"Disable background play" would disable PIP, and put the video on pause when ReVanced is exited. But the media notification would still be shown to re-play the video in background.

"Disable media notification" would only be unlocked if "Disable background playback" is enabled, well it would be like YouTube Free. No media notification, no PIP, no background play.

Of course all of this would be at the choice of the user.

I want this because I personally hate picture-in-picture, but I wanted to extend the idea a little bit with background play disabling.

You can already hide the background video and let audio play, by tapping the headphones icon in the pip window.
