CI: Generalize PhySim tests, run PhySims on Gracehopper

This changeset generalizes/harmonizes the CI infrastructure for physim
testing, and adds a new pipeline for physim tests on Gracehopper
machines.

Specifically:

- Refactor the existing CI code for running and analyzing physical
  simulators. The existing code assumed those tests are deployed using
  OpenShift. Instead, OpenShift/Helm-specificities (e.g., running a
  "release") have been removed, and instead of hardcoding the deployment
  of the physical simulators using a script for Helm, the function takes
  any script that can deploy using Helm/docker/from source. The overall
  appearance is the same.
- Add a new pipeline RAN-PhySim-GraceHopper-5G that executes physical
  simulators on gracehopper. Reporting is done in the same way as for
  existing physical simulators (e.g., like in the RAN-PhySim-Cluster-5G
  pipeline), but deployed in docker instead of helm.
  -> some tests don't work reliably on ARM yet and are skipped
- the RAN-gNB-N300-Timing-Phytest-LDPC pipeline has been reworked to use
  the same code for testing T2 offload, with ctest, and the same
  reporting.
- the CUDA LDPC test XML has been removed, as these tests don't work
  reliably.
- add a new macro add_timed_physim_test() that allows to define
  thresholds to be checked, so that ctest will check for them. see the
  documentation for more information
