Audio V4: Forward tracks attributes to the hal
Forward to the HAL the audio usage, audio content types and volume
of playback tracks to the stream out they are playing to.
Forward to the HAL the audio source and volume of record tracks
to the stream in they are playing to.
This will allow the HAL to better tune its effects and remove the need
to inject a fake effect (volume listener) to get the tracks volume.
