io_uring/epoll: add support for provided buffers

This will be a prerequisite for adding multishot support, but can be
used with single shot support as well. Works like any other request that
supports provided buffers - set addr to NULL and ensure that
sqe->buf_group is set, and IOSQE_BUFFER_SELECT in sqe->flags. Then epoll
wait will pick a buffer from that group and store the events there.
