switch to cesm-style field names in MOM6 cap

[DeniseWorthen]

• modify field names to use CESM-style field names. Field names were aligned with those in https://github.com/ESCOMP/CMEPS/blob/main/mediator/fd_cesm.yaml
• removes cesm_coupled restriction on enthalpy fields (fields are added to ufs field dictionary)
• two fields remain unresolved, sea_level and mass_overlying_ice, currently unused

@jiandewang I'm not sure of the status of this on the NCAR side. I think you were waiting on some in-progress work before they were able to test? We're looking to try to commit this early next week so we can move forward w/ sending the NCEP note out to the authors for review.

@DeniseWorthen let me coordinate with Gustavo, asking him to have a test on this PR. He is struggle with current NCAR PR which has trouble on our wcoss2 machine and it's not a simple task.
