Implement fix reorg and remove gfs-utils code

[WalterKolczynski-NOAA]

Description
Removes all of the code and scripts that were moved to the new gfs-utils repo and adjusts workflow scripts to build and use them from the new location.

Some of the build scripts had unnecessary calls to machine-setup that are removed because the lower-level script already has the same functionality.

This PR also includes updates to use the new fix organization. This includes the addition of a fix versions file, updates to the link script, and some changes in the fix directories used by scripts to account for files that have been relocated. The versions file sets the version number for each component of fix, so that fix can be more easily maintained and documented. The initial versions are all the same, and correspond to the old fix_NEW directory (other than some directories have been renamed or reorganized). Except gdas, which has already had a new set of fix files added. The fix update also required an update to UFS-Utils.

Finally, the link script has been updated to match the syntax of the rest of the build system (checkout.sh and build_all.sh). link_workflow.sh now detects the machine automatically instead of requiring an argument, and dev mode, which used to be set using emc as an argument, is now assumed. To run in ops mode (copy instead of link), the -o option is used. The full syntax is now simply:

./link_workflow.sh [-o]

Going to rerun a test or two over the weekend from a clean install to confirm things still work, but should be able to start reviewing.

Re-tests pass

looks good. Some comments.
This PR would have been much easier to review if it were separate PRs:

1. removing gfs-utils
2. fix reorg
3. updates to build scripts
4. updates to link_workflow.sh
