Update audio extension build configurations 

- Fix FLAC extension build (currently broken due to use of std::array,
  but fixed by migrating to NDK r20).
- Move opus and ffmpeg extensions to NDK r20. For ffmpeg, upgrade to
  release 4.2 which requires using libswresample and updates to the
  build script.

* Fix the start of audio getting truncated when transitioning to a new
item in a playlist of opus streams.
* Fix detection of Dolby Atmos in HLS to match the HLS authoring specification.
* Fix FLAC extension build
([#6601](https://github.com/google/ExoPlayer/issues/6601).
* Update the ffmpeg, flac and opus extension build instructions to use NDK r20.
* Update the ffmpeg extension to release 4.2. It is necessary to rebuild the
native part of the extension after this change, following the instructions in
the extension's readme.
