feature: GPU hardware detection for orchestrated backend

[romanc]

Description

This PR pulls out GPU hardware detection of the orchestrated dace backends from PR #465.

How has this been tested?

Mainly tested by running simulations as part of the June push (as part of PR #465). Added very simplistic test cases to cover the basics. It's kinda hard to check for hw detection (because you can't really know the hw you are running on).

Checklist

• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation (e.g. add new modules to docs/docstrings/)
• My changes generate no new warnings
• Any dependent changes have been merged and published in downstream modules: N/A
• New check tests, if applicable, are included

With this we currently still have no way of manually overwriting this, correct?

The more we do, the more we need a config of our own. But having this as the default is already better than what we had before

Correct - there's no way (without code changes) to change these defaults.

Agreed, the need for an NDSL-level config file gets more and more apparent.This is another good example.
