Update config_machines.xml

[altheaden]

This PR is just to update the config_machines.xml file from E3SM. I also updated some of the values we have in the files for each of the machines, as needed.

@xylar I set this PR to "in progress" for now because there are some machine files I haven't looked at yet to see if some of the older changes should be implemented. I'll put some notes here for you to look at and we can discuss. Also, since there are some pending changes in E3SM relating to Compy, we might want to include those in this PR as well.

After this PR is merged, I'll make two PRs for adding Aurora and Sunspot.

Note that there are some more recent changes to include:
E3SM-Project/E3SM#6596
E3SM-Project/E3SM#6603

@altheaden, this looks excellent so far!

@xylar I just rolled in the changes from the two E3SM PRs you mentioned and updated the appropriate files. I think all the spack files should be up to date now, along with config_machines.xml.

[xylar]

@altheaden, this all looks great to me! I think doing thorough testing of spack builds now using these changes will be too time consuming to be worthwhile. So my suggestion is that we merge these changes and then test them thoroughly the next time we need to update E3SM-Unified, Polaris or Compass.

I'm testing things out on Compy right now so we'll at least be able to see if those changes work.

[xylar]

I think this looks good. As long as you think it's done, let's go ahead and merge it.

[altheaden]

Sure, go ahead!
