alsa_sound: call voice volume api for direct output also

- Voip volume is not applied on direct output and as a result
  volume cannot be adjusted for some voicemail applications
  which opens direct output stream with mode set to IN_CALL.
- Voice volume is applied only for primary output and volume
  command is not sent to HAL for direct output.
- Call voice volume api for direct output as well from policy
  manager.

audio: Starting proxy thread when there is an active stream

- Proxy thread is started from DoRouting only when previous
  and current devices are external devices. When CS call
  is ended while BT Headset is connected, we get a route
  call to ear piece intermittently and then for BT A2DP to
  resume the music playback. As previous device is not
  external device, Proxy thread is not started automatically
  in this scenario. This is blocking pcm_write call for
  touch tones as ear piece is disabled and data is not
  consumed by proxy device as well

- Fix is to start proxy thread after the route call when
  pcm_write for any stream is in progress
