TRENDY2024 yr-1700 + historical cases with ctsm5.3 fsurdat (TRENDY2024_f09_clm60_ADspinup_<date_stamp> followed by SASU, pSASU, HIST)

[slevis-lmwg]

Description:
Year-1700 spin-up and 1701-2023 historical simulations for the TRENDY2024 intercomparison:

• 1700 ADspinup DONE
• 1700 SASU DONE
• 1700 pSASU DONE
• 1701-2023 HIST: TRENDY identifies this as S3 (S3_irrig because we forgot irrigation in the first iteration); @adrifoster will complete several other simulations, such as Control, S1, and S2.

@adrifoster when it's time to start SASU, please look at my user_nl_clm here:
/glade/u/home/slevis/cases_ctsm5.2/TRENDY2024_f09_ctsm52_SASU_20240729
I don't want to jinx it, but the simulation got past the error and is in progress now. The fix:
I upped the tolerance nnegcrit = -7.d0 from -6, which is what @ekluzek had recommended from the beginning, but I resisted...

In the same user_nl_clm, I changed reseed_dead_plants to false, as I did for SASU in #58

And remember the isotope stuff :-)
I did not include the latter since my simulations are for comparing ctsm5.3 to 5.2 but will not be used beyond that since we're moving to 5.3.

1. Result from reseed_dead_plants test: I see tiny diffs between my SASU runs with reseed_dead_plants = .true. and .false. so they are NOT bit-for-bit.
   @adrifoster and I decided to keep it set to .true. in SASU.

2. From discussion this morning: Let's coordinate what AD year we start SASU from. I've been using yr 300. Let me know if you decide on a different year.
   @adrifoster decided to extend AD to 400 yrs.
