Require ":authority" or "Host" in HTTP/3 and HTTP/2 requests.
Also, if both are present, require that they have the same value. These
requirements are specified in HTTP/3 draft 28.
Current implementation of HTTP/2 treats ":authority" and "Host"
interchangeably. New checks only make sure at least one of these values is
present in the request. A similar check existed earlier and was limited only
to HTTP/1.1 in 38c0898b6df7.
