audio: add implementation for TV related API
1. TunerConfiguration.
2. AudioDescriptionMixLevel getter/setter.
3. DualMonoMode getter/setter.
4. PlaybackRate getter/setter.
Test: TIS player with instrumented HAL
Test: atest AudioTrackTest#testTunerConfiguration
Test: atest AudioTrackTest#testDualMonoMode
