The VK_EXT_surface_maintance1 extension is an instance level extension, which means the loader will advertise support for it when at least one driver supports it. However, there is presently no way for an application to know which VkPhysicalDevice's will fill out the structs the extension defines and which VkPhysicalDevice's will ignore the structs.
Add support for testing the surface_maintenance1 implementation - making sure that a driver which supports the extension isn't affected and correctly filling out the structs for drivers which do and do not support vkGetPhysicalDeviceSurfaceCapabilities2KHR as well.
