Cleaned up land-increment namelist and script variable names.

[ClaraDraper-NOAA]

DESCRIPTION OF CHANGES:

Changed variable names for the land increments to be more consistent. Also added "gcycle_" at the start of several variable names, so that in the global_workflow it is clear that these actions are being requested from UFS_UTILS. This is in preparation for a future PR to global_workflow which will move some of this functionality into the model (using IAU).

TESTS CONDUCTED:

• Compile branch on all Tier 1 machines using Intel (Orion, Jet, Hera, Hercules and WCOSS2). Done using 0d1b2ea.
• Compile branch on Hera using GNU. Done using 0d1b2ea. global_cycle compiled with no warnings.
• Compile branch in 'Debug' mode on WCOSS2. Done on Cactus using 0d1b2ea with no warnings.
• Run unit tests locally on any Tier 1 machine. Done on Hera using 0d1b2ea. All tests passed.
• Run global_cycle consistency tests locally on all Tier 1 machines. Done using 0d1b2ea. All tests passed as expected.

DEPENDENCIES:

This PR is required for global_workflow PR 3295

DOCUMENTATION:

Note, the Doxygen did not compile correctly, but that is not related to this PR. It will be fixed in #1026.

Created as a draft, while I run tests in global_workflow.

@GeorgeGayno-NOAA I've confirmed this works with my pending global_workflow PR. Its ready to review.

[ClaraDraper-NOAA]

@GeorgeGayno-NOAA Is there anything else I need to do to get this merged?

Let me complete the tests on the machines you don't have access to. Then, we can merge.
