Some drivers may want to implement certain depth/stencil operations by
reinterpreting a depth/stencil format as a color format. This is not
strictly allowed by the Vulkan spec, so handle it separately.

Even though we can't really do the parsing on behalf of the driver (it's
too complicated), storing it in the vk_image lets us provide a common
implementation of vkGetImageDrmFormatModifierPropertiesEXT(). It'll
also be useful in the next few commits for swapchain images.

Currently, this is optional for drivers to carry around but it scrapes
up most of VkImageCreateInfo for you and parses a couple of extension
structs. We also add a few useful little helpers copied over from ANV.
