Fix Error Cannot prevent display sleep!, iina#3842

The commit in the pull request will:
- Change SleepPreventer.preventSleep to only display an alert once per
  IINA invocation
- Change Utility.showAlert to support a suppression button
- Add a button to the alert to allow the user to permanently suppress
  the alert
- Change the alert to include the error code returned by macOS

Additional text was added to the alert's message requiring localization.

This fixes how IINA reports a macOS power management failure.
The root cause of the failure is in macOS and must be fixed by Apple.
