Send ICMP errors when the network is unreachable
Before this change, we would silently drop packets when unable to determine a route to the destination host. This change brings us into line with RFC 792 (IPv4) and RFC 4443 (IPv6), both of which specify that gateways should return an ICMP error to the sender when unable to reach the destination. Startblock: has LGTM from asfez and then add reviewer ghanan PiperOrigin-RevId: 372214051
