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.
