AudioPolicy: enable apps to mute BLUETOOTH_SCO 

This change enables an app that has the MODIFY_PHONE_STATE
permission to mute the BULETOOTH_SCO stream.
The change adds specific handling in AudioPolicyManager
for the case in which volume index is 0 and stream type is
BLUETOOTH_SCO.
The permission check is done in the AudioService Java code for the
calling process.
