Setting up team's Mac mini

[chapman39]

Some things I've updated (am updating) during the process of setting up the Serac shared Mac mini.

Features:

• Update example mac spack.yaml
  • Separate Brew packages from /usr packages
• Update docs on how to build on Mac (package versions, adding additional packages for simpler concretizer tree, etc.)
• Fixes +devtools fails to concretize on macos #1206 by creating a Python venv before calling uberenv
• Setup Github runner testing Serac build/ tests (and TPL builds?)
• Document how to setup an additional user on the Mac mini

TODO:

• Add this branch to readthedocs
• Fix Serac build issues (see below)

Installing the latest llvm/ clang (@19.1.1) caused some problems building Axom, so to avoid that used brew install llvm@14. Here is the build error I got:

==> Installing axom-0.9.0.1-c2vvp4ki46aesbfiafjfnhpil35x3hqr [37/39]
==> No binary for axom-0.9.0.1-c2vvp4ki46aesbfiafjfnhpil35x3hqr found: installing from source

I think I resolved my python issues. Now I'm getting this...
