[develop] Re-enable and upgrade verif-global to use spack-stack 2.0.0, metplus 6, met 12

[DavidHuber-NOAA]

Description

This reenables verif-global on most platforms (except Orion and Hera). The upgrades to verif-global include an overhaul to port the system to MET/METplus v12.0.1/6.0.0 and new support for the satellite suite of products. This also applies fixes to the JGFS_ATMOS_VERIFICATION and verif-global scripts so that the metp* jobs can be run in parallel.

Caveats:

• Currently, v16 statistics are not compatible with this version of verif-global. New .stat files will need to be generated from v16 products in standalone mode to work with this.
• Relatedly, .stat files generated by older versions of EMC_verif-global are not compatible with this version. Users will need to generate new .stat files to compare against.
• Satellite step 1 verification is now enabled in verif-global, but is not (yet) part of the workflow. At this time, there are not plans to incorporate this feature into the workflow. Additionally, this feature (AFAIK) is only supported on Gaea C6.
• VSDB validation is no longer supported. All validation should be performed using the VALID method. Standalone config files will need to be updated accordingly.

Resolves #4127

Type of change

• Bug fix (fixes something broken)
• New feature (adds functionality)
• Maintenance (code refactor, clean-up, new CI test, etc.)

Change characteristics

• Is this change expected to change outputs YES (new GFS verification products)
• Is this a breaking change (a change in existing functionality)? NO
• Does this change require a documentation update? YES (updated HPC support checklist)
• Does this change require an update to any of the following submodules? YES
  • EMC verif-global Update Ursa, Hercules to spack-stack 2.0.0, remove support for S4, Jet, C5, and update WCOSS2 support to MET/METplus 12/6 EMC_verif-global#200

How has this been tested?

Will generate .stat files for metpg2g1, metppcp1, and metpg2o1 jobs for both C48_ATM and C96C48_hybatmDA cases (with the latter being extended 48 hours to verify pcp1 statistics) on

Converting back to draft. Some issues still remain to be addressed in verif-global and a new ECMWF and GFS v16 archive will need to be established. These are tentatively scheduled to be completed in June following the v17 retro evaluation.
