Fix VU error in swapchain creation tests

Fix VU error in swapchain creation tests

dEQP-VK.wsi.*.swapchain.create.image_sharing_mode checks if creating a
swapchain works with VK_SHARING_MODE_CONCURRENT, but passes a single
queue in the creation structure.

This commit changes the test to obtain all valid queue families for the
surface and uses all of them in the creation structure when using
concurrent sharing.

Affected tests:
dEQP-VK.wsi.*.swapchain.create.image_sharing_mode

Components: Vulkan
VK-GL-CTS issue: 2126
