Check if CTS has platform display for wsi-type

Vulkan driver can expose multiple VK_KHR_{platform}_surface extensions
and it's app responsibility to create platform display then create the
surface and pass it to vkCreate{platform}SurfaceKHR. But if CTS does
not have display for requested wsi type and extension is exposed, CTS
reports it as failure.

To fix this, if function createWsiDisplay fails then check whether CTS
has platform display available for requested wsi-type and if it does
then only report this as failure otherwise report it as unsupported.

Affects: dEQP-VK.wsi.*

Components: Vulkan, Framework

VK-GL-CTS issue: 1558
