Update MOM6 cap for 2-way ocean-wave coupling in HAFS

[binli2337]

The HAFS application in the ufs-weather-model will be updated to include 2-way ocean-wave coupling capability.

The related CMEPS component will updated to interpolate the Stokes drift components from WW3 grid to MOM6 grid. Since regional MOM6 domain and regional WW3 domain do not completely overlap, a missing value is assigned to the interpolated Stokes drift components in the non-overlapped regions (where the MOM6 grids are outside the WW3 domain). In the CMEPS component, the missing value is 9.99e20.

A short-term solution in the MOM cap is to convert the missing value to zero to prevent a model crash. A longer term solution is to merge the Stokes drift components from a global WW3 model with the related fields from the regional WW3 model in CMEPS.

A PR will be submitted to revise MOM6/config_src/drivers/nuopc_cap/mom_cap_methods.F90 to convert imported Stokes drift components from 9.99e20 to zero.
