Update JGDAS_ENKF_SFC job with COMIN/COMOUT prefix instead of COM

[mingshichen-noaa]

@mingshichen-noaa The prior incarnation of this PR made COM changes for the enkf_sfc and the enkf_update job but this new PR includes COM changes for the enkf_sfc and enkf_archive jobs. Is this intentional to have this change the archive scripts instead of the update scripts? Please confirm, thanks!

This PR (#3291) doesn't include "JGDAS_ENKF_UPDATE" job and associated scripts because previous PR (#3170) CI tests ran into trouble (test status of some tasks failed in Hercules). I am working on a new branch (feature/jgdas_enkf_update_job) in hera environment).
