Audio: fix voip calls over bluetooth headset.

Browse Source 
Current HAL start/stop bt_sco session only for incall mode -
rewrite logic to start/stop bt session when system switch to
one of the bluetooth devices.
Move bt_sco_active and pcm_sco_rx/tx to main audio_device structure.
Remove bt_sco_capture profile.
