46bc12867b Define new AudioControl HAL for automotive. 
This provides a mechanism for Android to interact with a car's
audio subsystem.
It is a partial replacement for the deprecated AUDIO_* properties in VehicleHal.
It also provides control over fade/balance.

Bug: 31623564
Test: build for bat_land.  VTS tests in future CL.
