Test the latest Intel oneAPI HPC Toolkit version with ssmp and psmp
using the new ifx Fortran compiler. The existing Intel tests use
still the old ifort compiler.
Rationale for this proposal: Docker is usually not provided on shared compute clusters, e.g. at HPC centres,
because docker runs a daemon with root privileges creating potential security vulnerability. By contrast,
podman is daemonless and more lightweight and is built on the same principles as Docker's API.
