audio: Update audio_policy file for tunnel mode audio playback

- Add ouput profile entry to the audio policy config file for
  tunnel mode audio playback.

Known Issues:
12 and 24kHz MP3 file are not supported in tinyCompress. So they
go through SW decode. Should add support in tinyCompress and then
add those as supported sample rates.

Bug: 8174410.
