Update omega calculation (NOAA-EMC#2751)

Add a parameter "pass_full_omega_to_physics_in_non_hydrostatic_mode" in FV3 namelist. It was set to "true" to use a new method to diagnose omega. This PR is based on the /ufs-community/ufs-weather-model#2327) Corresponding parameter changed in GFSv17 related regression tests ufs-community/ufs-weather-model#2373))
