Subject: yuzu-qt: Load Vulkan device info at startup

Loading it when the configuration opens now incurs a noticeable delay.
We also don't need to rediscover the same data repeatedly each time the
configuration opens.

Moves vulkan device info discovery to yuzu's startup as opposed to the
configure_graphics constructor.
