* Changes to re-enable aws-pcluster pipelines

- Use compilers from pre-installed spack store such that compiler path relocation works when downloading from buildcache.
- Install gcc from hash so there is no risk of building gcc from source in pipleine.
- `packages.yam` files are now part of the pipelines.
- No more eternal `postinstall.sh`. The necessary steps are in `setup=pcluster.sh` and will be version controlled within this repo.
- Re-enable pipelines.

* Add  and

* Debugging output & mv skylake -> skylake_avx512

* Explicilty check for packages

* Handle case with no intel compiler

* compatibility when using setup-pcluster.sh on a pre-installed cluster.

* Disable palace as parser cannot read require clause at the moment

* ifort cannot build superlu in buildcache

`ifort` is unable to handle such long file names as used when cmake compiles
test programs inside build cache.

* Fix spack commit for intel compiler installation

* Need to fetch other commits before using them

* fix style

* Add TODO

* Update packages.yaml to not use 'compiler:', 'target:' or 'provider:'

Synchronize with changes in https://github.com/spack/spack-configs/blob/main/AWS/parallelcluster/

* Use Intel compiler from later version (orig commit no longer found)

* Use envsubst to deal with quoted newlines

This is cleaner than the `eval` command used.

* Need to fetch tags for checkout on version number

* Intel compiler needs to be from version that has compatible DB

* Install intel compiler with commit that has DB ver 7

* Decouple the intel compiler installation from current commit

- Use a completely different spack installation such that this current pipeline
commit remains untouched.
- Make the script suceed even if the compiler installation fails (e.g. because
the Database version has been updated)
- Make the install targets fall back to gcc in case the compiler did not install
correctly.

* Use generic target for x86_64_vX

There is no way to provision a skylake/icelake/zen runner. They are all in the
same pools under x86_64_v3 and x86_64_v4.

* Find the intel compiler in the current spack installation

* Remove SPACK_TARGET_ARCH

* Fix virtual package index & use package.yaml for intel compiler

* Use only one stack & pipeline per generic architecture

* Fix yaml format

* Cleanup typos

* Include fix for ifx.cfg to get the right gcc toolchain when linking

* [removeme] Adding timeout to debug hang in make (palace)

* Revert "[removeme] Adding timeout to debug hang in make (palace)"

This reverts commit fee8a01.

* palace x86_64_v4 gets stuck when compiling try newer oneapi

* Update comment

* Use the latest container image

* Update gcc_hashes to match new container

* Use only one tag providing tags per extends call

Also removed an unnecessary tag.

* Move generic setup script out of individual stack

* Cleanup from last commit

* Enable checking signature for packages available on the container

* Remove commented packages / Add comment for palace

* Enable openmpi@5 which needs pmix>3

* don't look for intel compiler on aarch64
