Restrict nlmaps_atm2srf_conserve=.true. to v3HR grid

[wlin7]

Previously it was set to true for all configurations that use ne120 grid for atm.
This would affect EAM and EAMxx F-cases that use ne120. This change limits its
use to cases that use v3HR grid (ne120pg2 for atm and RRSwISC6to18E3r5 for ocean/ice).
It applies to both coupled and uncoupled configurations.

[BFB] No impact except for cases using ne120 atm grid with other ocean masks

---

Verified no impact for v3.HR.piControl-CMIP7 spin-up that uses ne120pg2_r025_RRSwISCE3r5,
previously also tested that nlmaps_atm2srf_conserve=.false. for F1850-CMIP7 that uses the same grid
when the use was restricted to coupled cases. This requirement is now dropped (removing the compset attribute)

I wonder if we do want this on for F-cases that use the same grid? EAMxx F-cases are using ne120pg2_ne120pg2 so would not pick this up just from the new grid spec.

I second Rob's suggestion - it should be based on the grid, but not compset. If using the a%ne120np4.+oi%RRSwISC6to18E3r5 grid in an F case, I think one would still benefit from nonlinear maps.

Note we had several fails (with ERROR: seq_nlmap_init_a2l_cons ERROR: Nonlinear map not set) reported on cdash that used ne120pg2_ne120pg2.F2010-SCREAMv1 -- this PR allows at least one of those tests to pass and remains BFB.

@rljacob @mt5555 . The grid in theory could be used, for example, to spin-up land that uses the same ocean mask.

[mt5555]

agreed. I'm suggesting that instead of:

<value grid="a%ne120np4.+oi%RRSwISC6to18E3r5" compset="_EAM.+MPASO">.true.</value>

we use:

<value grid="a%ne120np4.+oi%RRSwISC6to18E3r5" >.true.</value>

[wlin7]

agreed. I'm suggesting that instead of:

<value grid="a%ne120np4.+oi%RRSwISC6to18E3r5" compset="_EAM.+MPASO">.true.</value>

we use:

<value grid="a%ne120np4.+oi%RRSwISC6to18E3r5" >.true.</value>

I think this is good. The problem with the EAMxx F2010 test is mainly due to not having such a map, not that it couldn't use one. Changes submitted and the PR message to be updated.

Merged to next.
