RRFS–MPAS: Enable SFCR, FRICV, REFD (3d), and TKE; add processing of new fields (MIXL and RMOL)

[jaymes-kenyon]

This PR addresses issue #1451 for RRFS–MPAS applications. Specifically:

1. Output is enabled for surface roughness (SFCR), friction velocity (FRICV), full 3d reflectivity (REFD), and turbulence kinetic energy (TKE). These fields are processed using pre-existing codes in UPP.

2. New code is added to UPP to process the reciprocal Obukhov length (RMOL) and the mixing length (MIXL; as computed in the model).

These changes have been tested successfully on Ursa. A run directory (also visible from Hera) containing a netCDF file (model output) and an itag file is available at

@BenjaminBlake-NOAA Which g2tmpl version will be used for the new GRIB2 names in this PR?

[BenjaminBlake-NOAA]

@WenMeng-NOAA g2tmpl version 1.17.0 was released in October, so these new GRIB2 names/IDs will be part of the next g2tmpl release. I'm not sure when that will occur. So perhaps we should go with the most current version, 1.17.0?

@BenjaminBlake-NOAA It appears that g2tmpl/1.7.0 is included the spack-stack/2.1.0 release and is installed on some R&D machines. So these latest updates will be included the next g2tmpl release, 1.8.0?

[BenjaminBlake-NOAA]

@WenMeng-NOAA Glad to hear g2tmpl/1.17.0 is available in spack-stack/2.1.0. Yes I think these new updates will be included in g2tmpl/1.18.0. For now can we still update the params_grib2_tbl_new files with this PR so that the newly added MIXL field can be labeled with the correct table information?

@BenjaminBlake-NOAA Yes, that's a good approach.
