imports: sort imports everywhere in Spack (#24695)
* fix remaining flake8 errors * imports: sort imports everywhere in Spack We enabled import order checking in #23947, but fixing things manually drives people crazy. This used `spack style --fix --all` from #24071 to automatically sort everything in Spack so PR submitters won't have to deal with it. This should go in after #24071, as it assumes we're using `isort`, not `flake8-import-order` to order things. `isort` seems to be more flexible and allows `llnl` mports to be in their own group before `spack` ones, so this seems like a good switch.
