📄 Description

We prefer the nvcuda library, which reports driver versions. When we dropped cuda v11, we added a safety check for too-old drivers. What we missed was the cudart fallback discovery logic didn't have driver version wired up. This fixes cudart discovery to expose the driver version as well so we no longer reject all GPUs if nvcuda didn't work.

Fixes #11519
