[PATCH] dxgi: Allow sampling of Vulkan swapchain images for D3D12.

[Conor McCarthy]

Psychonauts 2 creates an SRV on a swapchain image and lack of
VK_IMAGE_USAGE_SAMPLED_BIT results in failure to create a Vulkan
descriptor.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Should adding VK_IMAGE_USAGE_SAMPLED_BIT be conditional on
swapchain->desc.BufferUsage having DXGI_USAGE_SHADER_INPUT set?
