Add libAudioHal AIDL interface placeholder

Add cpp backend only and ndk backend only conversion.
Add placeholder for DeviceHalInterface and EffectHalInterface.
Add several EffectHalInterface test cases to help testing.

Bug: 261129656
Test: Flash to Cuttlefish and run cts
Test: Flash to Panther and run audio use cases.
