Add Tuner framework AudioPresentation support 

DVB MPEG-2 transport streams can include audio preselection descriptors
for next-generation audio (NGA) as specified in ETSI EN 300 468. The
tuner framework audio preselection is mapped to media framework audio
presentations and made available via MediaEvent.

Bug: 264812332
Test: CtsTvTestCases:TunerTest#testAudioFilterStreamTypeConfig
      on aosp_cf_x86_tv with android.hardware.tv.tuner-service.example
