Introduce io_uring BPF struct ops implementing the loop_step callback, which will allow BPF to overwrite the default io_uring event loop logic. The callback takes an io_uring context, the main role of which is to be passed to io_uring kfuncs. The other argument is a struct iou_loop_params, which BPF can use to request CQ waiting and communicate other parameters. See the event loop description in the previous patch for more details.
