VK_KHR_incremental_present: Fix usage flags.

Besides swapchain support we also need
vkGetPhysicalDeviceImageFormatProperties support. Use just the
needed flags instead. As COLOR_ATTACHMENT is required in
VK_KHR_surface, we don't need to check for it.

Affected tests:

dEQP-VK.wsi.*.incremental_present.*

Components: Vulkan
VK-GL-CTS issue: 1395

Change-Id: I4dd0f95da0a8f31c11efe7ce58f12cfbe160a71e
