Pcluster local buildcache (#37852)

* [pcluster pipeline] Use local buildcache instead of upstream spack

Spack currently does not relocate compiler references from upstream spack
installations. When using a buildcache we don't need an upstream spack.

* gcc needs to be installed via postinstall to get correct deps

* quantum-espresso@gcc@12.3.0 returns ICE on neoverse_{n,v}1

* Force gitlab to pull the new container

* Revert "Force gitlab to pull the new container"

This reverts commit 3af5f4cd88.

Seems the gitlab version does not yet support "pull_policy" in .gitlab-ci.yml

* Gitlab keeps picking up wrong container. Renaming

* Update containers once more after failed build
