Add switches for execuables in rrfs-utl

[chan-hoo]

DESCRIPTION OF CHANGES:

• Add switches not to compile the unused executables in the RRFS workflow.
• The following source directories in rrfs-utl are not used in the scripts. However, all executables are compiled by default for development. When RRFS is delivered later, these can be turned off if they are not necessary.

gen_cs
FV3_ensmean_recenter
lakesurgery
radmon
rtma_minmaxtrh

TESTS CONDUCTED:

• On machines/platforms:

• WCOSS2

• Hera

• Orion

• Jet

• Test cases:

• Non-DA engineering test
• DA engineering test
• Other sample scripts:

ISSUE:

• Fixes the issue(s) mentioned in Need switches not to compile unnecessary executables in rrfs-utl #131

Dependency:

• Pre-requisite: Add switch for each executable not to compile unnecessary executables NOAA-GSL/rrfs_utl#56

@MatthewPyle-NOAA, RADMON is not compiled in this PR because its executables are not used in any scripts of the RRFS workflow. However, according to NOAA-GSL/rrfs_utl#43, it seems that we would need to compile it. Can you confirm this?

Retro experiments will need FV3_ENSMEAN_RECENTER, LAKESURGERY(?)

Is it possible to turn on all rrfs_utl executables by default and then use command line options to only build executables required by operation?

[chan-hoo]

@guoqing-noaa, good suggestion. I'll turn all of them on by default at this moment. We can adjust them later when it is delivered.

[MatthewPyle-NOAA]

@chan-hoo Sorry for the slow response. I believe that radiance monitoring will be done outside of the main RRFS workflow.

Realizing there is no reason to hold this one up - will approve and merge so @chan-hoo doesn't need to keep updating his branch.
