Subject: audout: Implement and fix some calls (#1725)

* audout: Implement GetAudioOutBufferCount, GetAudioOutPlayedSampleCount and FlushAudioOutBuffers

This PR implement audout service calls:
- GetAudioOutBufferCount
- GetAudioOutPlayedSampleCount
- FlushAudioOutBuffers

The RE calls just give some hints about no extra checks.
Since we use a totally different implementation because of our backend, I can't do something better for now.

SetAudioOutVolume and GetAudioOutVolume are fixed too by set/get the volume of the current opened track, previous implementation was wrong.

This fix #1133, fix #1258 and fix #1519.

Thanks to @jduncanator for this help during the implementation and all his precious advices.

* Fix some debug leftovers

* Address jD feedback
