Requires both VK_EXT_attachment_feedback_loop and VK_EXT_attachment_feedback_loop_dynamic_state to be provided by the driver. Otherwise it will fall back to the old code. Main benefit is for improving performance as it makes barriers cheaper and doesn't force us to unnecessarily interrupt renderpasses
