Fix to allow quilting with non-factors for layout

[chan-hoo]

Description

When the layout values (lx, ly) in the input file 'input.nml' are not factors of (npx-1) and (npy-1) respectively, quilting does not work.

Issue(s) addressed

• fixes fv3atm Fix to allow quilting with non-factors for layout #191
• fixes ufs-weather-model Move LSM vegetation lookup tables into CCPP, clean up RUC snow cover on ice initialization (remove IPD step 2) #244

Testing

It has passed the regression test on Hera.

It makes quilting work with non-factors for layout (two cases tested):

1. C96 conus, npx=211, npy=193, lx=4, ly=6
2. C96 conus, npx=211, npy=193, lx=8, ly=3

@chan-hoo just to confirm, you are not expecting this to change the results for thee regression tests, correct?

[chan-hoo]

You're correct. I think the regression tests would be set with factors for layout or quilting=false.

Thanks, @chan-hoo. That's good to know. I'll pull this into release/public-v2 right away. This removes the urgency of the commit for the develop branches.

I don't see any of the comments that were to be removed, all good.
