Implement VK_EXT_queue_family_foreign

This extension only actually adds an enum. The interesting behavior will come with image and buffer memory barriers describing an ownership transition between the real queue family and VK_EXT_QUEUE_FAMILY_FOREIGN. Depending on the platform, this may be nothing; may require cache maintenance operations; or may require a copy to/from an external buffer.
