erofs: Zstandard compression support
Add Zstandard compression as the 4th supported algorithm since it
becomes more popular now and some end users have asked this for
quite a while [1][2].
Each EROFS physical cluster contains only one valid standard
Zstandard frame as described in [3] so that decompression can be
performed on a per-pcluster basis independently.
Currently, it just leverages multi-call stream decompression APIs with
internal sliding window buffers. One-shot or bufferless decompression
could be implemented later for even better performance if needed.
