Description

This PR makes the following general changes:

• blacklist compiler-wrapper and intel-oneapi-compilers-classic from modules
• adds a uwtools variant to global-workflow-env; on by default but disable-able for stacks/sites where it's not needed
• use 'require' to set virtual package providers in common/packages*.yaml so that we don't have to configure/override these separately for various dependencies (and to avoid possible concretization quirks because of "providers" being a soft preference).
• move show_duplicate_packages output logic outside the show_duplicate_packages() function; also cleaned up some defunct logic left over from the previous iteration of this script

and the following Acorn/WCOSS2/NCO-specific changes:

• overhaul acorn and wcoss2 site configs, including reconciling them so they're basically the same apart from some NCO-specific package configuration
• overhaul of deploy.py: better logging; better integration with Spack Python API; move deployments.yaml under site config dir; validate env's by ensuring only user-specified packages can be built with GCC; add a "modules_flat/" directory that tests having all modulefiles in a flat structure (no compiler or mpi subdirectories)
• resurrect 'nco' template and add it to acorn deployments
• no more intel@2022 (per NCO & EMC agreement)
