Update Derecho site config

[climbfuji]

Description

1. Update Derecho site configuration to newer compiler versions, use native crayenv instead of ncarenv.
2. Submodule pointer update for spack to fix an issue on Derecho - never attempt to recursively scan the root filesystem (/). See spack PR filesystem.py: prevent recursively traversing the root filesystem spack#576 for more information and links to upstream spack discussion.

Dependencies

• Waiting on filesystem.py: prevent recursively traversing the root filesystem spack#576

Testing

• CI: Note whether the automatic tests (GitHub actions tests that run automatically for every commit) pass or not
  • GitHub actions CI tests pass
  • GitHub actions CI tests do not pass (provide explanation)
  • GitHub actions CI tests skipped (provide explanation if necessary)
• New tests added: List and describe any new tests added to GitHub actions
  • ...
• Additional testing: Add information on any additional tests conducted
  • Built oneAPI and GCC stacks on Derecho (unified environment). Tried jedi-bundle: Compiled and ran tests (skipped MPI tests that required qsub) with GCC. Compiled and ran into the well-known error in MPAS with oneAPI (but cmake step completed and most of the compilation succeeded as well). This is as far as I can go.
