This commit only replaces the bundled source and does not include any ZFS integration changes. Because the build depends on integration adjustments, it will fail until the accompanying integration commit is applied. Upstream release: https://github.com/facebook/zstd/releases/tag/v1.5.7 Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Alexander Moch <mail@alexmoch.com> Closes #18089
