Have long compset names that don't match -- fail with a graceful error

This came up in the context of #2561 where a CLM51%NONTHRO long compset failed to do the wrong thing, because NOANTHRO wasn't defined for CLM51.

The real problem is that it doesn't die with a graceful error -- and only does the wrong thing silently. And that's an important problem to fix.

The discussion in #2561 also says this..

> The same kind of problem shows up for DV and VIC for the setting of: CLM_BLDNML_OPTS, and for CLM_USER_MODS for CMIP6 and WACCMCMIP6 and FATES-SP.

For LND_TUNING_MODE invalid settings set an invalid value and hence die with an error. We should do something similar for these.

There's also some restrictions to configuration setup for description at the top that would catch certain issues -- but NOT all of them.
