Update contrib/libs/zstd to 1.5.7
Release highlights are:
* The compression speed for small data blocks has been notably (~10%) improved at fast compression levels.
* The `--patch-from` functionality of the zstd CLI ... had its speed reduced to uncomfortable levels. v1.5.7 largely mitigates the speed impact of high compression levels 18+
* The compression ratio has been enhanced slightly for large data across all compression levels,
