Setting up of run directory for Data Atmosphere configuration

[aerorahul]

Description

The atmosphere component is always ON in the workflow.
The NG-GODAS application of the ufs-weather-model does not have a live and interactive atmosphere. It compiles the with a data-atmosphere component from CDEPS.

The global-workflow does not have a DO_ATM switch.

Requirements
A DO_ATM switch shall be added to config.base
This switch shall be toggled based on APP.
The default value of DO_ATM shall be YES.
When APP=NG-GODAS, the value of DO_ATM=NO.

Update exglobal_fcst.sh and the scripts that it calls to implement the option for DO_ATM=NO for data atmosphere specific configuration.

The run-directory for DO_ATM=YES will be validated against current develop
The run-directory for DO_ATM=NO will be spot checked for correctness in the configuration.

It is not necessary to have the forcing files present in the run directory for the completion of this work.
This will be the focus of another issue.

Acceptance Criteria (Definition of Done)
APP=ATM|ATMW|S2S|S2SW allows for business as usual. (DO_ATM=YES)
APP=NG-GODAS allows for setting up of a run directory for DO_ATM=NO

IIRC, it was decided not to bring this into develop and a separate branch was made instead. That branch has since been cleaned up since Bin Li left.
