Add timers and overwrite capability for mod_def timesteps to meshcap

[DeniseWorthen]

Pull Request Summary

Adds run timers to the meshcap

Description

Adds generation of a timer log in the meshcap, which will report, for example, the time spent in modelAdvance as well as the time spent before starting the next Advance. The capability is added using a wrapper mod (mimicking the CICE wrapper mod) so that no additional ifdefs are required in the cap. The output generated in log.ww3.timer is

20210322   60000   21600 WW3 InitializeRealize time: 0.7798858
20210322   60000   21600 WW3 ModelAdvance time since last step:  4.489980
20210322   61200   22320 WW3 ModelAdvance time:  2.570183
20210322   61200   22320 WW3 ModelAdvance time since last step:  8.023816
20210322   62400   23040 WW3 ModelAdvance time:  1.164186

Also adds capability to over-write timesteps from the mod_def file with other values. See associated UWM ufs-community/ufs-weather-model#2086 for description of how this works.

Check list

• Branch is up to date with the authoritative repository (NOAA-EMC) develop branch.
• Checked the checklist for a developer submitting to develop.
• If a version number update is required, checked the updating version number checklist.
• If a new feature was added, a regression test for testing the new feature is added.

Testing

• How were these changes tested?
• Are the changes covered by regression tests? (If not, why? Do new tests need to be added?)
• Have the matrix regression tests been run (if yes, please note HPC and compiler)?
• Please indicate the expected changes in the regression test output, (Note the list of known non-identical tests.)
• Please provide the summary output of matrix.comp (matrix.Diff.txt, matrixCompFull.txt and matrixCompSummary.txt):

Testing in UWM ufs-community/ufs-weather-model#2086 has no impact on baselines.

I will get these started as well!

[MatthewMasarik-NOAA]

The code changes are only in the meshcap code, so standalone testing is not necessary. UFS-WM testing has confirmed that no RT baselines change.

Approved.

Combined with #1163; Closing.
