Changes

Spack updates (#1158)

* Initial changes to get code working with the new spack+module system. See https://github.com/larson-group/sys_admin/issues/829

* Changes for restart_gfortran_test

* Possible fix for tuning test

* Part 2 to tuning test fix. It's unclear why the recent change caused top level directory for these stages to be in clubb, rather than the parent directory. Perhaps it has to do with the triple quote

* Adding the mkl flag back to intel config scripts. It's still usable when adding -m or --mkl_lapack to our compile script call, and now we have intel-oneapi-mkl installed because wrf needs it.
