More MARBL updates for CESM3

[mnlevy1981]

Need to set some grid-specific BGC parameters for the tx2_3v3 grid, and also NCAR/MOM6#434 changes how MOM6 expects to some BGC forcing data to be provided (so this PR updates MOM_input). There might be some other parameter changes coming from @kristenkrumhardt, she is tuning MARBL and I don't know if the MOM6 parameters should be set ParamGen or if we'll just update the default values in the Fortran code. I'll take this out of draft mode when all of that has been finalized.

I'm running aux_mom on 1fa7196 right now, but splicing together the in-progress testing with results from before I added the MARBL conditional to setting MARBL_IC_MIN_VAL (which had a bunch of NLCOMP failures because I added MARBL_IC_MIN_VAL to every test instead of just the ones with MARBL) the failures are

4	FAIL
	2	NLCOMP (FAIL)
      1 SMS_Ld1_D.TL319_t232.C1850MARBL_JRA.derecho_intel
      1 SMS.TL319_t232.G1850MARBL_JRA.derecho_intel
	2	BASELINE (FAIL)
      1 SMS_Ld1_D.TL319_t232.C1850MARBL_JRA.derecho_intel
      1 SMS.TL319_t232.G1850MARBL_JRA.derecho_intel

These are expected; the NLCOMP failures come from the new MARBL_IC_MIN_VAL and the baseline failures are a combination of setting MARBL_IC_MIN_VAL (so the initial conditions in the tests are slightly different) and also the new tunings that are part of the updated MARBL tag.

I did also see

3	FAIL
	1	COMPARE (FAIL)
      1 PET.TL319_t232.C_JRA.derecho_intel
	1	TPUTCOMP (FAIL)
      1 ERI.TL319_t233.G_JRA.derecho_intel.mom-debug
	1	BASELINE (FAIL)
      1 PET.TL319_t232.C_JRA.derecho_intel

I'm not sure what happened with the PET test, so I'll see if it's reproducible before digging in... and my experience is that TPUTCOMP failures are intermittent / can be affected by machine and network use

The PET test passes now:

I can confirm that only the expected tests are failing:

4	FAIL
	2	NLCOMP (FAIL)

@alperaltuntas this is ready for review. Summary of changes (this is the intent of the changes, if anything goes against this list it's likely a mistake that I'm happy to fix):

1. testlist_mom.xml: move all aux_mom_MARBL tests from tx2_3v2 to tx2_3v3 (does not change pr_mom, aux_mom, prealpha, or prebeta test lists)
2. .gitmodules, MOM6/, and externals/MARBL update MOM6 to dev/ncar_260710 and MARBL to marbl0.50.0
3. MOM_input.yaml: updates to support MARBL compsets with tx2_3v3
   • IC file was moved to grid_indpt since it's 1°x1° and MOM6 handles horizontal interpolation
   • data from MARBL_FESEDFLUX_FILE, MARBL_FESEDFLUXRED_FILE, and MARBL_FEVENTFLUX_FILE were combined into single MARBL_FE_INTERIOR_SOURCE_FILE. There is a brand new file for tx2_3v3 and also I combined the data from the three existing tx2_3v2 files into a single file for that resolution (there are still a few tests with MARBL on the v2 grid in the test suite)
   • Introduced MARBL_IC_MIN_VAL, which is necessary (but not sufficient) to pass DIMCSL test with MARBL compset
   • Created river nutrient forcing files on v3 grid
4. input_data_list.yaml: mirrors changes to variables in MOM_input.yaml that deal with new forcing files (IC files in grid_indpt/, new iron forcing setup, new river nutrient files)
