FMS2: Move FMS domain calls to MOM infra

[marshallward]

The set_domain and nullify_domain calls used in FMS1 IO now pass through the MOM domain infra. Explicit references to the internal mpp_domain have also been removed.

This should not be merged until the corresponding MOM PR has been handled:

NOAA-GFDL/MOM6#394

@marshallward could you add one more mod to this PR? The following line is causing a compile issue, but the restart interfaces are not "used" anywhere in the file and the line can be deleted:

use fms_io_mod,        only : register_restart_field, restart_file_type

https://github.com/NOAA-GFDL/SIS2/blob/dev/gfdl/src/ice_ridge.F90#L27

BTW, since the required MOM6 PR is handled this one can go in now, right? Thanks.

[marshallward]

Oops, I meant for that line to also be removed, thanks Niki.

[marshallward]

Thanks @nikizadehgfdl the line has now been removed. I believe this is ready to be merged once it's been reviewed and tested.

I have run CM4 and OM4 tests with this PR, both with infra/FMS1 and infra/FMS2, and with old and new fms tags and they all worked fine.

These changes would prevent the use of SIS2 with any versions of MOM6 that predate the incorporation of PR #394 into MOM6. This is a horrible practice, dictated by changes to the FMS interfaces in callous disregard for the continuity of projects using FMS.

Unfortunately, I do not see any alternative that would allow us to use the latest version of FMS2 but to accept these disruptive changes. However, I would note that MOM6 PR#394 is relatively simple, so it should be possible to cherry-pick it onto any older versions of MOM6 (or the version currently on the main branch) that we would need to use with the latest version of SIS2.

This PR has passed the SIS2 pipeline testing at https://gitlab.gfdl.noaa.gov/ogrp/SIS2/-/pipelines/20010.

Although there are potentially disruptive version dependencies on MOM6 code versions, this commit will work with the version that is on the MOM6 dev/gfdl branch as of June 30, 2023, and will hopefully be merged onto the main branch of MOM6 soon.
