Small changes to exp2 ceiling and SLP output

[EricJames-NOAA]

This PR includes a small revision to the RAP/HRRR exp2 ceiling diagnostic to improve performance for the RRFS. It also removes MLSMA (MAPS SLP reduction) output, based on conversations with Jacob Carley and Andrew Benjamin (NCEP) and Curtis Alexander (GSL). It also corrects the GRIB2 name for the MAPS SLP (should be MSLMA instead of PRMSL based on https://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_table4-2-0-3.shtml) in post_avblflds.xml.

The changes were tested for RRFS_B (CONUS 3km) on Jet; the only change to output was removal of the MAPS SLP, and changes in the exp2 ceiling field.

@EricJames-NOAA Could you sync your branch with the latest commit of the develop branch from the authoritative UPP repos.?

[WenMeng-NOAA]

@EdwardColon-NOAA Please let me know if you have comments on grib2 name change of MAPS SLP reduction in 3drtma control file.

[EdwardColon-NOAA]

The change in the ceiling diagnostic seems reasonable. As long as the update is reflected in the 3drtma control file, there should not be a downstream issue with the analysis.

[WenMeng-NOAA]

@EricJames-NOAA Could you add change logs in the source code you modify?

There are following changed results from RT tests from hrrr/rap:

@EricJames-NOAA Can you confirm the above changes are expected? Thanks!

[WenMeng-NOAA]

The grib2 name of MAPS SLP reduction in 3drtma will be changed from PRMSL to MSLMA.

@EricJames-NOAA Can you confirm the above changes are expected? Thanks!

@WenMeng-NOAA yes, that's consistent with my tests! The GSL exp2 ceiling diagnostic is labeled HGT/PRES on cloud base according to post_avblflds_raphrrr.xml. That is the only field I expect to change from this change. Thanks.

[WenMeng-NOAA]

@EricJames-NOAA Can you update post_avblflds.xml based on my comments and sync your branch with latest commit from the develop branch? Thanks!

[EricJames-NOAA]

@WenMeng-NOAA I think I just synced with the latest commit from the develop branch. I already added the NCEP table info line for post_avblflds.xml...please let me know if there are other changes needed for this file.

[EricJames-NOAA]

@WenMeng-NOAA looks like one of the checks failed...maybe I did something wrong when syncing my branch with the latest EMC develop...let me know what you recommend...

@EricJames-NOAA I saw it. Thanks for clarifying.

@EricJames-NOAA I re-run the failed CI test. Now all CI tests look good. I would assume that's github issue. All your changes look good to me.

@WenMeng-NOAA thanks! Sounds good.

The UPP RT tests were completed on WCOSS2, Hera and Orion. The baselines for rap/hrrr and 3drtma will be updated with this PR.

This PR is ready for merging.
