Add selectPresentation API to IAudioTrack
The Java AudioTrack interface has a setPresentation API. This
calls the setParameters API in IAudioTrack. However, this does
not eventuate into a call into the android.hardware.audio@4.0
IStreamOut selectPresentation API.
Add selectPresentation API to IAudioTrack and call down to the
android.hardware.audio@4.0 IStreamOut selectPresentation API.
Translate into calls to setParameters API for legacy HAL
interfaces.
