QUIC: ignore duplicate PATH_CHALLENGE frames.
According to RFC 9000, an endpoint SHOULD NOT send multiple PATH_CHALLENGE
frames in a single packet. The change adds a check to enforce this claim to
optimize server behavior. Previously each PATH_CHALLENGE always resulted in a
single response datagram being sent to client. The effect of this was however
limited by QUIC flood protection.
Also, PATH_CHALLENGE is explicitly disabled in Initial and Handshake levels,
see RFC 9000, Table 3. However, technically it may be sent by client in 0-RTT
over a new path without actual migration, even though the migration itself is
prohibited during handshake. This allows client to coalesce multiple 0-RTT
packets each carrying a PATH_CHALLENGE and end up with multiple PATH_CHALLENGEs
per datagram. This again leads to suboptimal behavior, see above. Since the
purpose of sending PATH_CHALLENGE frames in 0-RTT is unclear, these frames are
now only allowed in 1-RTT. For 0-RTT they are silently ignored.
