Added simulated audio input devices to car audio configuration. This
devices can be used for any audio zone in particular but are mostly set
to target zone 0 and zone 1. Also added osillator struct to keep track
of phase and current phase increment (e.g ~frequency) to keep track of
current phase changes in simulated input device.
Test: m -j, run emulator

- rear seat buses (with "rear" in its address) uses right channel
- left channel otherwise
This behavior is enabled only if ro.aae.simulateMultiZoneAudio property
is turned on. To switch the behavior back and forth during runtime, one
has to restart the audioserver as well as car service after changing the
value via `adb shell setprop <key> <value>`. The most convenient way
would be to enable this flag at boot time as following
```
emulator -prop ro.aae.simulateMultiZoneAudio=true
```

Also, uses broadcast radio to better demonstrate audio patch as an
end-to-end case. We can further surface pseudo broadcast radio audio
stream.

Change log
- audio_vbuffer in its own source and header files
- a pcm is shared via ext_pcm by multiple audio streams
Known issue
- Audio is distorted if multiple audio streams try to play
simultaneously. This is due to lack of proper audio mixing and will be
fixed in a future CL
