Add Github Action on macOS and clang

[aerorahul]

DESCRIPTION OF CHANGES:

This repository is missing a CI for macOS.

This PR:

• adds a github action for macOS with clang.
• uses v3 of cache in the workflows.
• Removes old and broken workflows.

TESTS CONDUCTED:

The changes in this PR have no impact on current configuration on on-prem systems. No tests were conducted on HPC platforms.

Additional github action for macOS + clang was added.
The software dependencies are built with spack and are cached.

ufs-utils fails to build on macOS which highlights that the ufs-utils is not portable to macOS platform. This
PR does not fix this problem, it only baselines a workflow for macOS. I

The Clang macOS Build and Test / ufs_utils step of https://github.com/ufs-community/UFS_UTILS/actions/runs/5883650102/job/15958702123?pr=842 is expected to fail.
UFS-utils does not build on macOS.

I suggest disabling this workflow until someone fixes ufs-utils to be macOS compatible.

Seems like the errors are caused by a c99 flag. Can that be turned off?

Thanks for getting the CI system working again!!

@edwardhartnett Yes. I tried that, but there are more (other) errors and I don't want to capture enabling CI on macOS and fixing errors on macOS in the same PR. It is also a rabbit-hole I do not wish to enter. I will leave that to someone else.
