Also fix AARCH64 build to be neon optimised where available, this leads to a 72% improvement in decoding speed.

- Update README_MOZILLA for adding mp3 support, and add some clarifying text.
- Clang-format config.h for easier reading since it is our file, not ffmpeg's.
- Use sort -d -u to produce defaults_disabled.* files so linux and macOS
produce same files.
- Change MOZ_FFVPX_FLACONLY to MOZ_FFVPX_AUDIOONLY since it indicates flac
and mp3 decoders.
- Rename config_flac.h to config_audio.h

With the move to clang-cl as default compiler on Windows, those are no longer necessary.

Consequently, this removes:
- MOZ_LIBPRIO, which is now always enabled.
- non_msvc_compiler, which is now always true.
- The cl.py wrapper, since it's not used anymore.
- CL_INCLUDES_PREFIX, which was only used for the cl.py wrapper.
- NONASCII, which was only there to ensure CL_INCLUDES_PREFIX still
worked in non-ASCII cases.
This however keeps a large part of detecting and configuring for MSVC,
because we still do need it for at least headers, libraries, and midl.

In libavcodec 58 and later, the old avcodec_decode_video2 is broken and only return the first visible frame found after a VP9 super-frame.
This resulted in some YouTube videos for about 10% of the frames to never be returned.
Only the new API properly behaves so we upgrade our code to use it.

This mostly removes static strings declaration, replacing them with null pointers.
It does cause to switch to algorithms that are more geared toward space saving than speed gain. However, those are mostly in hash calculations, which the FLAC decoder doesn't use.

This drops the size to libmozavcodec to around 1MB down from 4MB.

For now this is a C decoder only and FFmpeg isn't optimised to only decode flac (both vp8 and vp9 C decoders code is included, however they aren't enabled).
