Updating MOM_input_template_500 with wave coupling configurations

[junwang-noaa]

Description

In PR#1916, the MOM_input_template_500 is not updated to the one used in the global workflow because the one in GW changes results due to the change for EPBL_LANGMUIR_SCHEME variable when "USE_WAVE" is set to false. Wave group will confirm how to set this variable with "USE_WAVE" setting. A follow up PR will be made to make MOM_input_template_500 consistent in the model and GW.

I heard back from GFDL today and setting EPBL_LANGMUIR_SCHEME=ADDITIVE, is consistent with the OM4 settings, so I think the best thing to do will be to add this setting to the C48 coupled test with the 5 deg ocean. I have a branch that has this update along with updates to make the MOM templates consistent with updates for DA being added in NOAA-EMC/global-workflow#1944 as requested by @aerorahul. I'm currently running a full set of regression tests with both sets of changes which can be found here: https://github.com/JessicaMeixner-NOAA/ufs-weather-model/tree/feature/mom6sync Once regression tests finish I can make a PR. Baselines for the C48 test will change because of the change in EPBL_LANGMUIR_SCHEME and the updates from NOAA-EMC/global-workflow#1944

@JessicaMeixner-NOAA Thanks for checking with GFDL. I want to confirm that the "EPBL_LANGMUIR_SCHEME" is an independent variable to USA_WAVES. In other words, either USE_WAVES is .true. or .false., we should use EPBL_LANGMUIR_SCHEME="ADDITIVE", is that correct?

[JessicaMeixner-NOAA]

@junwang-noaa yes, it is independent. From Brandon:
The Langmuir number is set by Qing Li's theory waves formula when there is no wave model.

The regression tests ran overnight and had a few unexpected failures since I had not added the new MOM settings in the datm tests section in default vars. I'll get that updated this morning and re-run tests. PR should be submitted late today or Monday.

@JessicaMeixner-NOAA Thanks for updating the template.

@aerorahul FYI. With this MOM input template update, G-W can use the model templates. The difference is that model uses the variables for the IAU configurations.

Thanks for the work @JessicaMeixner-NOAA.
Thank you for the confirmation @junwang-noaa
I will have a companion global-workflow issue using these templates for the next sprint.
