vulkan_tests_results

Hi.
When running the Wine's Vulkan test, I've encountered some failures when
running on a machine with dual graphics. They appear to be caused by Wine not
filling device LUIDs for the discrete GPU, only the primary integrated (Intel)
one. This happens even if you set preference for the discrete GPU and filter
out other GPUs with some envars (__NV_PRIME_RENDER_OFFLOAD=1
__GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only).
This causes an issue in World War Z, as it requires device LUID to be filled,
and falls back to its inferior DX11 renderer if the LUID is zero-ed out.
I've attached a text file with output from the vulkan test running with
different combinations of these filtering envars and with none of them.
I should note that this is not related to bug 49631, these tests were done on a
different machine and during the tests for this bug report virtual desktop was
disabled.
