Add an AGL tool to test audio control HAL
This program can be used on the AGL side to acquire audio focus
using Audio Control HAL APIs, and play a sound file (WAV format)
once focus is acquired.
It is a proof of concept meant for demo flows, rather than a production
hardened tool for safety critical usages.
Bug: 168727790
Test: build and flash on device then run
android_audio_controller_test -f /tmp/chime.wav -s vsock:1000:9410
while Android has focus via KitchenSink
observe Android focus loss & car chime played
