FMS mpp domain creation is done in the `clone_MD_to_d2D` function, and currently an IO domain is always created within the MPP domain. This has caused problems with single-PE runs in FMS1, where the `write_field` logic was not able to reach the part which removes halo data if an IO domain was present, and halo data was being written to the restart files. This issue arose when `PARALLEL_RESTARTFILES` was set to `True` for single-PE tests. This does not appear to be a problem with FMS2, and no action is needed by the FMS team.

There was a problem hiding this comment.
The logic behind this PR is sound, and it should be merged in as it has now passed both TC testing and pipeline testing at https://gitlab.gfdl.noaa.gov/ogrp/MOM6/-/pipelines/13911.
