leaudio: Apply QoS settings based on use scenarios

Use scenarios (voice, media, etc..) can be classified into low latency or high reliability type. Values defined in BAP spec can be applied to those use scenarios accordingly. In future when more use scenarios are added, QoS settings can be made per-direction basis for those use scenarios.

Test: atest --host bluetooth_le_audio_test
