Modified RUN1 to load balance

[aoloso]

Subroutine RUN1 of GEOS_CICE4ColumnPhysGridComp is modified to for load balancing similar to what was previously done for subroutine CICECORE in subroutine RUN2.

FWIW, these changes provide a slight speed up:

All runs are for 1 month with cas.

Ocean Model | NCPUS | mean wallclock time before update (number of simulations) | mean wallclock time after update (number of simulations) |
MOM5 | 1440 | 145 min (1) | 136 min (2) |
MOM6 | 1440 | 193 min (3) | 196 min (1) | **there was a variability of > 20 min in my runs before update.

Thanks for tidying up other components besides sea ice (CICE4). (Reviewing on behalf of the @GEOS-ESM/ocean-team)

@aoloso, thanks for this PR. But I see you also brought in changes to other components not related to CICE4 load balance. I am not able to review all of them.

All sea ice components are fine. Approve.
