ZStandard is a modern, high performance, general compression algorithm. It provides similar or better compression levels to GZIP, but with much better performance. ZStandard provides a large selection of compression levels to allow a storage administrator to select the preferred performance/compression trade-off. This commit imports the unmodified ZStandard single-file library which will be used by ZFS. The implementation of this new library is done with future updates of zstd in mind. For this reason we integrated the code in a way, that does not require modifications to the library. For more details, see `module/zstd/README.md`. The library is excluded from codecov calculation and cppcheck as unaltered dependencies do not need full codecov or cppcheck.
