This patch just adds a preliminary Zstandard support to erofs-utils
since currently Zstandard doesn't support fixed-sized output compression
officially. Mkfs could take more time to finish but it works at least.
The built-in zstd compressor for erofs-utils is slowly WIP, therefore
apparently it
From: Gao Xiang
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

Only four lcluster types here, remove redundant code.
No real logic changes.
