Ci reactivate darwin pipelines (#48453)

* ci: darwin stacks: update tags following system updates

* disable SPACK_CI_DISABLE_STACKS; only enable *darwin* stacks for testing

* manually chmod u+w tmp/ before cleanup due to issue#49147

* comment out failing specs for now

* re-enable logic for disabling stacks

* add explanatory comment for darwin after_script additions

* remove more darwin-only targetting

* restore build_stage to default location

* move build-job-remove out of individual darwin stacks into darwin top level config

* keep build_stage in $spack/tmp for now
