Description of the changes in your PR

• Followup to Better player error handling #7142
• Created a ErrorUtil class that contains the three ways to report an error:
  • openActivity: just opens the error activity as always
  • showSnackbar: just opens the error snackbar as always
  • createNotification: creates a notification with a description containing the usual error message, and a title explaining that by tapping on the notification you can report the error. The notification disappears upon tapping, and is set to IMPORTANCE_LOW like other NewPipe notifications so that it does not make sounds.
• Correctly prevent exception from being serialized in ErrorInfo, eliminating the need for EnsureExceptionSerializable (see commit message for more info)
• Remove PlayerErrorHandler and instead always show error notification when an error occurs in the player. Also remove the related "report player error" setting.
• Add two new options in debug settings to show an error snackbar or create an error notification

APK testing

The APK can be found by going to the "Checks" tab below the title. On the left pane, click on "CI", scroll down to "artifacts" and click "app" to download the zip file which contains the debug APK of this PR.

To test I suggest using the "Crash the player" button from #7142 or triggering #7302 @litetex

Code LGTM only minor things.

Tested it a bit, seems to work as expected.

I'm glad that you managed to get rid of the ugly exception workaround 😄

Only one thing is a bit confusing:
When e.g. a player error happens, the player just stops and I don't notice the notification at the top (in particularly when the notification bar is already full due to my phones notch).
So I think showing a toast that says "Unexpected error occurred, tap notification for details" would be great. I would show the toast whenever a new error notification is shown.

I agree, I'll improve this

You can also test the player error by trying to play in background this live: https://www.youtube.com/watch?v=Q3uwXbkheDo
