tests: Add a helper script to use prebuild components

This is a helper script that does basically what's already being done by
the s390x CI, which is:
* Move a folder with the components that we were stored / downloaded
  during the GHA execution to the expected `build` location
* Get rid of the dependencies for a specific asset, as the dependencies
  are already pulled in from previous GHA steps

For now this script is only being added but not yet executed anywhere,
and that will come as the next step in this series.
