quic: stop guarding ngtcp2_recv_stop_sending callback field

[Renegade334]

When we updated ngtcp2 to v1.25, a version guard was added to the recv_stop_sending field of our ngtcp2 callbacks structs. At the time, we didn't implement it and we just passed nullptr, so it wasn't necessary to break existing shared builds over it.

Now that we have migrated to using this callback, and session functionality depends on it, we shouldn't be allowing older shared builds to omit it.

Drive-by: label the remaining omitted callbacks for ease of maintenance.
