Handle audio presentation switching in AC-4 TS

Audio preselection descriptors(APD) can switch mid-stream in AC-4 TS.
Detect change in APD by monitoring PMT version & CRC. Update new
audio presentation information to the stream metadata so that
MediaExtractor.getAudioPresentations() always returns a latest
audio presentation available.
