WIP: Update darwin ci

[Yurlungur]

PR Summary

This PR updates the Darwin CI. I do the following:

• Move away from spack land. Instead use modules + a few pre-installed files.
• Simplify machine config file
• Move to declarative machine files per target architecture
• Target AMD-EPYC + A100 instead of Power9 + V100

I am, however, still having trouble getting the parthenon performance reporting app to behave.

PR Checklist

• Code passes cpplint
• New features are documented.
• Adds a test for any bugs fixed. Adds tests for new features.
• Code is formatted
• Changes are summarized in CHANGELOG.md
• CI has been triggered on Darwin for performance regression tests.
• (@lanl.gov employees) Update copyright on changed files

If anyone knows how to resolve the failures on the performance reporting tool I would welcome some help on that.
