update setup procedures for LADAS

[saraqzhang]

for integrated setup of adas and ldas, modifications and updates are implemented in fvsetup and several scripts and rc files that are used in the fvsetup procedure. the modifications to other related external components and ldas are updated by pull requests to the corresponding repositories.

@rtodling @gmao-jstassi @gmao-rreichle This PR ( draft) contains the updates we presented last meeting (1/22/2025). these updates have been tested in a hybrid 4dnvar experiment ( integrated setup and one-day cycling) . Next we are going to implement the update to make lfo forcing as bkg files in the setup, workflow and archive. There will be corresponding development and updates in ldasGC src.

@saraqzhang : I added a very minor commit (removing Haswell and Skylake choices) and a couple of inline comments

@gmao-rreichle @gmao-jstassi @rtodling
we added the further updates for land forcing "lfo" as bkg in setup and in hybrid da cycling. The updated system passed the tests on setup and a hybrid LADAS cycling.

@saraqzhang, I added a few inline comments. I might be wrong on some (or even all of them), but take a look and see if any of the suggested changes make sense

@saraqzhang, @gmao-jstassi, @rtodling : I see that fvsetup maintains lists of files for the ADAS components. E.g., for chemistry:

GEOSadas/src/Applications/GEOSdas_App/fvsetup

Line 922 in a4e6c0c

@chem_files = qw ( Aod3d_1064nm.rc

Looking towards improving the LDAS integration going forward, do we need to think about having such a list for the LDAS files? For example, LDAS needs nml input files that define the land model perturbations and the obs that it assimilates. (These files are in plain vanilla Fortran nml format, but they're essentially rc files.)

I am working on this ... please don't make changes anymore @saraqzhang @gmao-jstassi

[rtodling]

I changed references to older architectures in fvsetup to what they were ... I will make sure those get changed ( and removed, as this originally attempted) but in a general wya - w/ the *input files changing accordingly.
