[feature/update_to_spack_v1] Shorten module paths for spack-generated modules and meta-modules

[climbfuji]

Description

This PR shortens the module paths for the modules generated by spack module [tcl|lmod] refresh and spack stack setup-meta-modules. It does so by implementing a compiler- and MPI-name translation and shortening the path where the modules are generated. This is done in multiple places:

configs/common/modules_lmod.yaml
(configs/common/modules_tcl.yaml)
spack-ext/lib/jcsda-emc/spack-stack/stack/meta_modules.py

While this solution comes with a certain amount of code duplication, I consider it as the best option because any other solution would have required changes to the spack code itself. Also, we rarely make changes to these names or add new compilers and MPI providers, thus the maintenance effort is low.

While working on this, I realized that the ecmwf-atlas --> atlas translation never worked as intended, because it was missing the MPI module dependency. I checked and the spack-generated modules were named ecmwf-atlas before this PR was made (at least for tcl modules). I therefore removed this mapping, since the module name ecmwf-atlas apparently worked fine until now.
