Add WW3 daily-averaged wave fields needed for the NorESM merge

[alperaltuntas]

Description of changes

This PR is needed to sync WW3 forks of CESM and NorESM. The NorESM WW3 cap exports 11 new Sw_*_avg fields and expects the mediator to output them in a daily-averaged auxiliary history file. This defines those fields in fd_cesm.yaml, and drops the stale ww3 histaux overrides that were still requesting the old instantaneous fields.

Specific notes

This PR must be evaluated and merged in conjunction with:

• merge Noresmhub noresm branch to dev/unified WW3#42
• merge noresm WW3_Interface into main WW3_interface#19

No answer changes

The only user interface changes is the default value and description of histaux_wav2med_file1_doavg.

@mvertens recently made some changes to the ww3 aux hist fields - see #677. It looks like this PR may need to be updated to merge cleanly with that one... but I also wonder if the changes from @mvertens make some of this unnecessary???

Once you reconcile this with @mvertens 's changes, I'm fine with this PR as long as @mvertens is good with it - so no need for further review from me.

@billsacks - I am wondering actually why none of the latest CMEPS changes that I brought in made it into this PR. But that said - those changes become irrelevant if the noresm defaults are picked up - which looking at this PR seems to be the case. We no longer need the noresm/cesm distinction - since only the noresm one is kept.
@alperaltuntas - I am wondering why the differences with cmeps main did not show up in the PR differences. I accepted the PR, however, given the fact that we just want the noresm defaults.

[alperaltuntas]

@mvertens I started off of cmeps1.1.48 but then merged the latest main before submitting the PR, so I am not sure why your changes don't show up. Happy to revise it if you have a suggestion, but you are right that we are adopting NorESM defaults, so we probably no longer need noresm/cesm distinction (at least for the time being).

[alperaltuntas]

@mvertens @billsacks I just realized I previously merged a stale main, so that's why @mvertens's latest changes didn't show up. I merged with the latest main this time, and will run a few tests to double check things.

[mvertens]

@alperaltuntas - thanks for clarifying - this all makes sense. I'm happy to review again.

[alperaltuntas]

Update: with the latest merge commit, all of my tests passed. So, this PR is ready again for review.

[billsacks]

Thanks, @alperaltuntas . I'm going to remove myself as a reviewer, deferring to you and @mvertens on this. It seems like you could potentially remove the coupling_mode selector from histaux_wav2med_file1_flds if those are back to being the same for cesm & noresm, but I'll let you and @mvertens make that decision.

[mvertens]

@alperaltuntas - thanks. This looks correct to me now.
