Closes #18111

Note that the non-empty part doesn't matter right now because of #18129.

Can you elaborate more on why you only return if nread > 0? I would expect this to just pass through nread so long as src == dst.

Because of #18079. After investigating the Readers in the stdlib, I think that UdpStream is the only one that can ever return Ok(0).

UdpStream is already a lossy convenience wrapper.

I've updated the PR. UdpStream is now deprecated for the reasons outlined in the docs.
