Add option for CRUJRA2024, add corresponding compsets for Clm6 and Clm5

Did not change the defaults and, therefore, did not change answers.

We will make a separate answer-changing PR to address Clm6 tests that do not specify the datm input, so that they get CRUJRA2024 instead of GSWP3v1. I.e. at that time we will change the defaults.

FATES default parameter file update

This tag updates the default parameter file for FATES bringing in a
number of updates:
   - adds parameters for land use grazing
   - updates the FATES z0mr turbulence parameters for consistency with
     CLM
   - adds FATES pft-dependent btran model switches for a forthcoming
     update
   - updates the default hydro solver switch to Picard 2D

This also updates the default FATES tag which includes two issue fixes
and introduces
the aforementioned land use grazing capability.

Change choice of pressure in CLMU building energy model

In the CLMU Building Energy Model (BEM), the choice of pressure for calculating indoor air density is changed from standard pressure to bottom layer of atmosphere pressure of the corresponding grid cell.

Answers change.
