Subject: [PATCH] audio: add implementation for TV related API

1. AudioDescriptionMixLevel getter/setter.
2. DualMonoMode getter/setter.
3. PlaybackRate getter/setter.

Test: TIS player with instrumented HAL
Test: atest AudioTrackTest#testTunerConfiguration
Test: atest AudioTrackTest#testDualMonoMode
Test: atest AudioTrackTest#testAudioDescriptionMixLevel
Test: atest AudioManagerTest#testGetAdditionalOutputDeviceDelay
