vulkan/wrapper: Sort physical devices

Browse Source 
Sort discrete GPUs over the rest, Nvidia over AMD, AMD over Intel, Intel
over the rest. This gives us a somewhat consistent order when Optimus
is removed (renderdoc does this when it's attached).

This can break the configuration of users with an Intel GPU that
manually remove Optimus on yuzu. That said, it's a very unlikely to
happen.
