Update EE2 Environment Variables: Replace NET-Specific (VARgfs) with Global (VARglobal)

[AntonMFernando-NOAA]

DESCRIPTION OF CHANGES:

• This PR updates multiple scripts in UFS_UTILS to adopt the EE2 global workflow naming convention. Modifications were made to test scripts for global_cycle, ice_blend, and snow2mdl, as well as to driver scripts in the ush directory. These changes ensure that the UFS_UTILS submodule is fully compatible with the global-workflow naming standards proposed in issue #4410. All NET-specific environment variables have been replaced with global equivalents, improving clarity, consistency, and maintainability across the workflow.

TESTS CONDUCTED:

• All available CI tests were run successfully in the global-workflow repository using the updated UFS_UTILS submodule.

• Compile branch on all Tier 1 machines using Intel (Orion, Jet, Ursa, Hercules and WCOSS2).

• Compile branch on Ursa using GNU.

• Compile branch in 'Debug' mode on WCOSS2.

• Compile with Doxygen on any machine with no errors.

• Run unit tests locally on any Tier 1 machine.

• Run relevant consistency tests locally on all Tier 1 machines.

@BrianCurtis-NOAA @DavidHuber-NOAA tested this with the G-W CI tests on WCOSS2, and they passed successfully. Ready to merge.

@BrianCurtis-NOAA @DavidHuber-NOAA Currently, g-w is still using an older UFS_UTILS hash cdfd24c. Once this PR is merged, g-w will be updated to point to the latest UFS_UTILS develop branch (which will include this change) by PR #4540.

To ensure compatibility with the latest UFS_UTILS develop branch, several ush scripts in g-w need to be updated. Those changes are included in PR #4540.

Ursa is back and all testing passed. Is there anything else needed on the GW side before merging?

Thank you, @BrianCurtis-NOAA, for testing. That’s all for now. Once this PR is merged, I’ll add the new hash to the GW branch (#4410) and proceed with addressing the GDAS app.

@DavidHuber-NOAA, please let me know if anything looks out of order.

Looks great, thanks @AntonMFernando-NOAA!
