Allow io_uring_submit batching just ahead of poll/select

Let's add a mode (enabled via the LIBOSMO_IO_URING_BATCH environment variable), where we don't call io_uring_submit() after every operation we add to the submission queue. Rather, do that once before we go into poll.

This should massively reduce the amount of io_uring_enter() syscalls we're seeing.
