Merge "SpatialAudio: Set low latency allowed signal at startSession The logic... 

Merge "SpatialAudio: Set low latency allowed signal at startSession The logic is that to send FREE and LOW_LATENCY to audio at startSession, if bt receives setLowLatencyModeAllowed(true) before start session. If the parameter false, or bt doesn't receive the signal at all, then bt sends FREE to audio."
