icmp: add support for extended echo request and echo reply messages

This change implements support for extended echo request and reply
messages, and interface identification object that can be used to test
the status of a probed interface via a proxy interface from a probing
interface as defined in RFC 8335.

It's package user's responsibility to make a complete RFC-compliant
PROBE initiator implementation using ipv4, ipv6 and icmp packages of
x/net repository.

Fixes golang/go#24440.
