[develop] Add more plotting WE2E tests

[EdwardSnyder-NOAA]

DESCRIPTION OF CHANGES:

Adding more plotting tests as discussed in #741. This PR ensures that each coverage, comprehensive, and fundamental suites have at least one experiment that runs the plot_allvars task.

While testing this PR, I noticed that setting the plotting script to the regional domain for the RRFS_AK_13km domain results in a very unusual png output. This will be addressed in a later PR and will be tracked via issue.

Four more tests with generating graphics, that's awesome! Maybe the corresponding tests without the graphics could eventually be retired from the test suites.

@EdwardSnyder-NOAA I was able to successfully test the updated grid_RRFS_CONUS_13km_ics_FV3GFS_lbcs_FV3GFS_suite_GFS_v16_plot test on Jet. It successfully passed and saw that the test produced the expected PNG plots. Approving PR.

@EdwardSnyder-NOAA There were a few failures in the Jenkins tests, but these failures were expected:

On Cheyenne GNU - the nco_grid_RRFS_CONUS_3km_ics_FV3GFS_lbcs_FV3GFS_suite_GFS_v15_thompson_mynn_lam3km test failed intermittently in the run_post tasks. This test has been failing since it was introduced in the WE2E coverage tests.

On Gaea - following the PrgEnv update last week, neither the SRW or weather model are able to build or run on the machine. Working with Natalie to correct this.

On Hera Intel - the grid_RRFS_CONUS_13km_ics_FV3GFS_lbcs_FV3GFS_suite_RRFS_v1beta test failed in run_fcst (issue #731).

Since only expected tests failed and the updated plotting tests all passed and produced PNG files, so I will go ahead and merge this work now.
