This PR disables HDR when driver doesn't support
`VK_EXT_swapchain_colorspace`. It could be that Windows detect support
(DirectX) and allow users to enable HDR. But that it isn't supported by
the Vulkan part of the driver.
In case of Windows there might be an issue with using SRGB non
linear on F16 swapchains where somewhere an additional transform is
being performed. After adding support for other color spaces we should
remove the support of this swapchain configuration.
