Reduce log message noise

[samsrabin]

As discussed at CSEG meeting 2024-06-18, reducing unnecessary messaging is a CSEG goal for CESM3.

Things to consider for each message:

• Is it needed at all?
• Can it be changed to only show if the XML DEBUG setting is true? (By wrapping in #ifndef NDEBUG/#endif)
• If it's currently in cesm.log, should it be moved to lnd.log?
• If every process is printing it, can it be set so that just the primary process does?

Messages to consider:

• clm: leaving fates model (lnd.log, every process)—especially strange considering there's no "entering" message. Get rid of this
• CN Soil matrix solution is off (cesm.log, every process) get rid of this (also filed at cleanup cesm log #2717)
• pes participating in computation for CLM and table (lnd.log), maybe we keep this? yes
• Init2: calling FireInit (cesm.log, every process)

Noting that this still has not been addressed as of ctsm5.3.014

@samsrabin is this something that can be easily addressed and put on b4b-dev?

[samsrabin]

Yes, definitely. However, I'll need to wait until b4b-dev gets the eventual fix to the Izumi nag failures introduced (probably) with the Bytnerowicz update.

[wwieder]

Makes sense. Seems like the nag bug will be addressed this week

@wwieder and @samsrabin we just merged the fix to b4b-dev. So b4b-dev is ready to have PR's added to it again.
