The encoding.DecompressZSTD* consistently updates the vm_zstd_block_decompress_calls_total metric.
Also make the follwing improvements after the commit 10f7cd2ffc:
- Add encoding.DecompressZSTDLimited() function and use it instead of zstd.DecompressLimited,
so it properly updates vm_zstd_block_decompress_calls_total metric.
- Clarify description for the encoding.DecompressZSTD* and zstd.Decompress* functions.
