Describe the solution you'd like
Add a volume change event.

Describe alternatives you've considered
Using video element events, but this adds complexity and makes things more difficult than needed.

Additional context
#2496

Thanks!

We are exposing a setVolume method in Mediaplayer.js. This method can be called directly by the app. Consequently the app is aware when the volume changes as the previously mentioned method should be used. What would be the reason to add an event for that?

@dsilhavy I'm using custom controls, which need listeners to update the state. This is really helpful, as I can now listen on buffer, can*, playback, stream, text, track, etc.

If it were part of playback/stream, one can listen and simple update the state:

state.muted = player.value?.isMuted();
state.paused = player.value?.isPaused();
state.volume = player.value?.getVolume();

Implemented in #3969. Can you please confirm that this is the desired behavior.
