Add 'netcdf' and 'grib2' to input 'source' options in regional IC/LBC routines

[chan-hoo]

Description

• Add 'netcdf' and 'grib2' to the input 'source' option in the regional IC/LBC routines of atmos_cubed_sphere.
• Since the logic of 'netcdf' or 'grib2' in the code is the same as that of 'nemsio', these three types are put in the same category.

Issue(s) addressed

• fixes Regional IC/LBC routines in atmos_cubed_sphere allow only 'nemsio' as global attribute 'source' #281
• fixes (dev/emc) Regional IC/LBC routines allows only gfs nemsio string as global attribute source (reopened) NOAA-GFDL/GFDL_atmos_cubed_sphere#97
• fixes Regional IC/LBC routines in atmos_cubed_sphere allow only 'nemsio' as global attribute 'source' ufs-community/ufs-weather-model#523

Testing

• Passed the regression test of the ufs weather model on WCOSS (dell/cray) and Hera with intel compiler.
• Completed a LAMDA test successfully with 'netcdf' input files from GFS.

@DusanJovic-NOAA @MinsukJi-NOAA, due to a critical technical issue, I'll close this PR and re-open it.
