This patch fixes a sign bug, in both MCT and NUOPC, when accounting for the latent heat from fprec and frunnoff.
Following MOM6's definition, both fprec and frunoff are > 0 into the ocean. Therefore, the latent heat associated with these terms should be < 0 (i.e., the ocean must lose heat to melt the ice). The diagnostics for these terms (latent_fprec_diag and latent_frunoff_diag) have also been corrected.

This PR will change answers for all CESM/MOM6 tests.

Pinging a few folks from EMC since they also use the nuopc cap @DeniseWorthen, @jiandewang

associated with these terms should be negative.

@gustavo-marques thanks for the information, I assume this fixing will be pushed back to GFDL after their FMS2 PR

@jiandewang yes, but this might take some time to happen.
