Before this change, it was unclear who owned the platform specific VkSurfaceKHR object, leading to a double-free in the error path for devices with no Vulkan support. This change moves the ownership to the platform specific code. Add vk.EnumeratePhysicalDevices while here (refactor was part of debugging of the double-free).
