Use uv_udp_try_send() to reduce latency when sending UDP

Ondřej Surý requested to merge ondrej-use-uv_udp_try_send into main

Use the synchronous UDP sending when possible as this should reduce the latency as we are going to avoid polling the network interface on the send.

Unfortunately, it's not yet possible to call the isc_nm_send() callbacks synchronously on success, so we still have to allocate uvreq and call the send callback asynchronously.
