1. Import unmodified ZStandard v1.4.4 …

   This imports the unmodified ZStandard source to contrib/ which will be
   used by ZFS. This code shall not be modified in any way to keep it
   easily updatable.
   
   Only the required files from lib/ are imported.
   
   contrib/zstd is excluded from codecov calculation as dependencies don't
   need full codecov.

5. Add a build intermediary lib for zstd …

   This add a new build intermediary libzstd. This allows us to keep zstd
   cleanly separated from libzpool and to override the frame-size compiler
   option without for zstd only. (This is needed due to unused coude in
   the unmodified zstd source.)
