fix some grids
required by mpas ocean.
Allow these grids to be fetched from DIN_LOC_ROOT instead of only from the path "/glade/p/univ/ucsu0085/inputdata..." This does not guarantee those files exist!
Removes leading zeros from the 'mpasa...' portion of aliases to better match the atm and lnd grids used. Change the 'not_compset=...' to match CESM. Also added 'EarthWorks specific ...' comments around aliases added for mpas-ocean and river run-off mapping.
The default ocean/seaice files for 15km have been updated to use a new one that does not initially generate unstable transients. These modifications are in the mpas-ocean, mpas-seaice, and ccs_config components.
An entry is created for the regionally refined 60-3km grid with the refinement over the western U.S. The 3.75 and 7.5km hires meshes are updated to new, stable initial conditions.
Catch up to development, especially to cesm3_0_beta06 version.
New 30km ocean files are now set as the default. The new files have had the domain adjusted so that seaice does not freeze the entire column.

Some help reviewing from @jedwards4b would be appreciated! (Can't assign reviewers.) |

These rules for MPAS-Ocean and MPAS-SeaIce are better handled in the Depends.* files for each compiler than in cime:CIME/Tools/Makefile.

@jedwards4b the Depends.{nvhpc,gnu} files have been updated following this comment in ESMCI/cime #4807. |

This PR adds grids and aliases for those commonly used by the MPAS Ocean (MPAS-O) and MPAS SeaIce (MPAS-SI) components.
This was tested by hand in a CESM sandbox with some other relevant changes also present. No problems were observed with ccs_configs while running some spot-check tests using MPAS-O and MPAS-SI, while running aux_cmeps through
create_test, or when running the cime scripts_regression_tests.py.
