Vulkan: Use a separate queue for presenting.
Before this change, we simply fail if the device does not expose one queue family that supports both graphics and present. Currently this is fine, since devices tend to lay out their queues in this way. NV, for instance, tends to have one queue family for all graphics operations and one more for transfer only. However, it's not a hard requirement, and it is cheap to use a separate queue, so we might as well.
