Upgrade WM to spack-stack 2.1.0

[gspetro-NOAA]

Description
Contains code changes required to upgrade the WM to spack-stack v2.1.0:

• Remove sst_ncep & sst_anom, which were removed from FMS in PR 1695: Remove sst_anom and sst_ncep from the amip_interp code.  FMS#1695

Fixes #409

How Has This Been Tested?

TBD.
Will run WM RT and communicate issues with developers, who may put in their own PRs.

Could ncep2fms subroutines be removed all together? It looks like their main purpose was to compute sst_ncep which is now removed. So now they are being called to only compute some local coefficients that are not used, unless I am missing something.

@RatkoVasic-NOAA Do you know the answer to this?

@gspetro-NOAA , probably, I'm not sure if that is used in FV3 anymore. That should be question for https://github.com/NOAA-GFDL/GFDL_atmos_cubed_sphere maintainers. I see couple of names in log: Vithika Shah, XuLu-NOAA, Bin Liu, Philip.Pegion, Brian Curtis, ...

I don't believe we are using external_sst() anymore at GFDL as we have replaced this with data_override calls in our models.
