### Describe the problem area

Currently there are only selective app ops with brief description of what they do like almost all Dangerous app ops, request_install_package, wake_lock etc. But they are only a few and it's very hard to decide which app ops to disable and which to not.
Like once I disabled TAKE_AUDIO_FOCUS app ops for a browser app and I was unable to play videos in the browser with audio on (video plays default at mute and when I unmute, it pauses) and I spend alot of time figuring that it was this app ops that was causing the issue.

### Current documentation if it present

Just add description to other app ops as well which currently don't have any.
