QUIC: removed "quic_mtu" directive.
The directive used to set the value of the "max_udp_payload_size" transport
parameter. According to RFC 9000, Section 18.2, the value specifies the size
of buffer for reading incoming datagrams:
This limit does act as an additional constraint on datagram size in
the same way as the path MTU, but it is a property of the endpoint
and not the path; see Section 14. It is expected that this is the
space an endpoint dedicates to holding incoming packets.
Current QUIC implementation uses the maximum possible buffer size (65527) for
reading datagrams.
