Prefer discrete GPU over integrated one
Prefer discrete GPU over integrated one

This unblocks launching on Linux laptops that default to the integrated
GPU which can not handle Vulkan in many instances.
Ideally a manual device selection, or an option for the optimal selection
strategy should be provided via CLI or config, but for the time being
this will unblock the Linux devs.

Partially addresses #42348 and #43714
