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 Mac devtool issues by creating a Python venv before calling uberenv (Fixes +devtools fails to concretize on macos #1206)
• Removes BoundaryCond.DirectTrueDofs test, which was failing on MacMini only (Fixes boundary_cond test fails on macos #1207)
• Setup cron job testing Serac build/ tests
• Document how to setup an additional user on the Mac mini

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
==> Ran patch() for axom
==> axom: Executing phase: 'initconfig'

==> Error: ProcessError: Command exited with status 2:

functional_basic_dg has failed in CI for me twice today. Retry resolves it but just wanted to let you know @samuelpmishLLNL
