Updates to UPP for RRFS applications (#3)

* Updates to UPP for RRFS applications:
1) Adding a RRFS-specific .xml control file and a corresponding .txt flat file.  Note that script changes (pending) are needed to leverage the new flat file.  However, this code will work in current real-time configurations.
2) Adding GSL experimental ceiling diagnostics, GSL visibility diagnostic, and GSL sea-level pressure reduction (MAPS).  Also adding TKE and aerosol number concentrations.
3) Code clean-up for ceiling-related diagnostics; added comments, etc.
4) Removing several non-needed variables, originally inherited from FV3-SAR community configuration.
