Description

Provide full CUDA errors for device scan messages.

Motivation and context

How has this been tested?

CI checks.

While this does not provide a better message in #1802 as I hoped, the code does work and may provide a better message for someone in the future. I tested it by triggering an error manually before the message is formatted.
