Add audio configurations API to audio control HAL

The API will be used to obtain the car audio configuration:
- Audio device configurations
- Audio mirroring devices
- Audio zone information
- - Audio zone fade configuration
- - Audio zone configurations
- - Input audio devices
- - Audio zone info

Bug: 359686069
Test: m -j, presubmit
Flag: EXEMPT HAL interface
