Display CUDA device information.

e.g. NVIDIA GeForce RTX 2070 (capability 7.5, 7979 MiB), CUDA driver
11.7, runtime 11.7

This is displayed in hyperdrive text preambles as well as calibration
solutions.

NVIDIA terms and conditions are now included in the repo and CI outputs,
as the code to determine the device details was derived from an official
NVIDIA example.
