One-line Summary: API compatability with FATES V2 nutrient dynamics

Purpose and description of changes
8
+
----------------------------------
9
+
10
+
This set of changes allows CTSM to continue API compatability with changes to the FATES API. FATES has updated its nutrient dynamics routine, and required a modification to the test environment, some minor updates to variable dimensions in the history, and a call to a new FATES history routine. Implicitly, the updating of the FATES tag introduces new content in the FATES model since the last API update (mostly bug fixes).

Significant changes to scientifically-supported configurations
The changes here will only affect FATES simulations. Any FATES simulation will be affected. Carbon-only FATES simulations will not have qualitatively different results since the last API update (but will have bit-for-bit differences). Nutrient enabled FATES simulations (not fully coupled to CLM, only via prognosed plant N,P boundaries), and FATES-Hydro simulations (bug fix) will be different.

This set of changes comes with an updated FATES parameter file. This includes format changes only. No changes to variable values were introduced. Format changes are relegated to new parameters and/or name changes only. These changes are encapsulated in: fates/parameter_files/archive/apichange_24.2to25.xml

Changes to tests or testing: New history variables were added to the FATES PRT2 user_nl_clm.
fates tests: (give name of baseline if different from CTSM tagname, normally fates baselines are fates-<FATES TAG>-<CTSM TAG>)
