ELM-side changes for outputting biophysics variables by land use type

[ckoven]

This pull request passes HLM biophysical landuse variables into fates to by output as diagnostic variables along FATES dimensions. Thefates_cold_luh2 test mod is updated to include these new diagnostic variables. This also updates the fates_cold_allvars testmod to include new history variables added with NGEET/fates#1485.

This PR is the ELM-side code changes associated with FATES PR NGEET/fates#1536.

[non-BFB] for FATES due to field lists

This pull request should come in after #7954

@rgknox this is ready for review. I'm going to kick off fates and e3sm_land_developer tests on perlmutter once my baselines are completed.

Regression testing the fates testmod list against the baseline for sci.1.90.1_api.43.1.0 is B4B with the expected exception of FIELDLIST differences in the luh2 testmods and the allvars testmods.

[glemieux]

Regression testing the e3sm_land_developer list on pm-cpu against the master baseline is underway.

[rgknox]

This is straight forward and sensible, thanks for submitting

[glemieux]

Re-running e3sm_land_developer regression tests post fates-side update and rebasing against master.

Regression testing on perlmutter against master baseline is B4B with the expected NLCOMP diffs for a subset of the fates test.

@peterdschwartz I'll give you a ping once we've integrated the fates side and after I've updated the commit hash here.

[glemieux]

@peterdschwartz this is good to integrate.
