DTS-HD MA with core maps to both DTS-HD and DTS. Add wiring to support more than one alternative MIME type.
Android supports a seperate AudioFormat.ENCODING_DTS_HD_MA and a MediaCodec mime type with ;profile=dtsma since SDK 34, but ExoPlayer wasn't using this even though the platform docs explicitly say to use the new encoding for DTS-HD MA. Implement detection of DTS-HD MA and add plumbing to use this constant where available, and fall back to previous behavior of using ENCODING_DTS_HD otherwise for backwards compatibility with devices that weren't updated to support the new constant/MIME type. DTS-HD MA exists in two versions, in multi-layer version where fallback to DTS decoders is valid and in a single-layer version where it is not. Add detection for this and change fallbacks accordingly. Issue: androidx#2487
