DNS: Add DoT ALPN (RFC 7858)
This codepoint was not registered in RFC 7858, but requested later by
Jon Reed at 2019-12-12, in "[dns-privacy] ALPN protocol ID for DoT":
Tne primary use case we have is supporting both DoT and DoH on port
443, when port 853 is blocked between clients and the servers (this
is by mutual agreement, as discussed in RFC 7858 ยง 3.1).
