update land-related collections in HISTORY.rc.tmpl to match M21C file specs

[gmao-rreichle]

The primary objective of the present PR is to bring the file specs changes from M21C into "develop". The corresponding (although somewhat outdated) M21C PR is #356 (merged on 8 Dec 2022).

Labeled as 0-diff under the assumption that tests have their own HISTORY.rc files.

These changes still need to be propagated into the custom HISTORY.rc templates to be reflected in GEOS products. The key target is FP. For FP, however, the file specs change has to be mid-stream, which creates its own complications. Nevertheless, it is critical that FP be updated sooner rather than later. The changes implemented in this PR and the related PR below include bug fixes (in land budget variable meaning) and improved user friendliness of several land-related variable shortnames and longnames.

I can never remember. Does FP use HISTORY.rc.tmpl or the ones with hours like HISTORY_FP.rc.03z.tmpl?

As far as I know, HISTORY.rc.tmpl is just the generic template that's not really used by anything. I'm not sure which HISTORY templates are used by FP, and I would be surprised if they're not coming in from some other repo (likely somewhere in the ADAS). In any case, all I can do is to update the generic template. Rob and the ADAS team will have to work these updates into the FP tag when they're ready for the changes to take effect.

FP uses the HISTORY.rc files with the time stamps included. The HISTORY changes depending on which cycle is being run due to the differences in the forecast lengths and the implementation of the FSOI.

Note mid-stream changes to HISTORY in FP are typically avoided and the best choice would be to include this as part of the major overhaul that will come next year when the resolution changes. If it must get in sooner, I will have to review the impact on the file spec to notify users. The product involved may have to be dropped from the OpenDAP time series as well.

Learned something new. Okay, so HISTORY.rc.tmpl is sort of a "Ops-like" HISTORY but not the "real" history used.

So maybe eventually the changes from @gmao-rreichle here can be ported over to the timestamp-histories when @rlucches, et al are ready.
