SDK / exoplayer

Without this annotation it seems that `SimpleExoPlayer` effectively
'un-deprecates' the method, specifically:
* A usage of these methods isn't flagged by Android Studio if the
  declared type is `SimpleExoPlayer` (up-casting to e.g.
  `ExoPlayer.VideoComponent` results in the warning showing up).
* The `SimpleExoPlayer` javadoc doesn't mention this method is
  deprecated:
  https://exoplayer.dev/doc/reference/com/google/android/exoplayer2/SimpleExoPlayer.html#addVideoListener(com.google.android.exoplayer2.video.VideoListener)
* The Metalava API output for `SimpleExoPlayer` doesn't show these
  methods as deprecated.
