FATES hydro test update

This minor update reverts a temporary work around for FATES hydro system tests.
The FATES tag is updated to capture the FATES-side fix to the issue that predicated
the temporary testing workaround.

Merge b4b-dev 20241220

This tag is in the temporary branch tmp-241219, while master remains
"locked" in preparation for a cesm tag.

The process was unorthodox, in that I (slevis) received a code review
and made revisions and retested after having started the first merge
steps.

iRpointer files for restart now have the simulation timestamp in the …

…filename

Add the simulation timestamp to the rpointer files. Also update submodules with this change
in CMEPS and CDEPS as well as updated cime to handle it. See the notes below for an explaination
about this.

Add a "clm" level directory under usermods_dirs so that the component where user-mods reside
is declared and to make them function the same as test-mods.

Update cdeps with cam7 nextsw cday changes

Update CDEPS with changes for CAM7 nextsw_cday handling. This changes answers
for CPLHIST cases. We also changed the cam7LndTuningMode tests to turn this on
for DATM to more closely match what CAM7 does.

Bring in several fixes for testing in the previous cesm3_0_beta03/04 …

…tags

Fix a list of issues mostly for testing that came in with the cesm3_0_beta03 and cesm3_0_beta04 tags
for the science "chill" deadline bringing in the baseline science capabilities needed for the cesm3_0 release.

List of things:

- New polarcap grid
- Fix use_init_interp for several resolutions that had problems
- Remove clm5_1 physics option
- Newly needed surface datasets added to auto build in Makefile for mksurfdata_esmf
- Fix several individual tests that were failing
- Update to submodules to ones roughly based on cesm3_0_beta04
- Add graceful error checking to the FATES parameter file tests that will get it working in some cases

Merge b4b-dev

Bring in latest b4b-dev branch to main CTSM development.

- Update git-fleximod
- Fix equation number in tech note
- Implement urbanl and urbanc coszen filters
- Make ALBGRD and ALBGRI active by default
- Some adjustments to control pylint for the RXCROPMATURITY python tests
- Run_sys_tests: Print test list in --verbose/--debug.

Update temperature cost function for symbiotic Nfix in FUN

Updates temperature cost function of Nfix using lab measurements from
Bytnerowicz et al. (2022), see Supplementary Table 3.

This has the new option hardcoded on, and it needs to move to a namelist
item. There are likely other changes that should happen as well before
coming to main-dev.
