MINOR: quic: Increase the size of handshake RX UDP datagrams
Some browsers may send Initial packets with sizes greater than 1252 bytes
(QUIC_INITIAL_IPV4_MTU). Let us increase this size limit up to 2048 bytes.
Also use this size for "max_udp_payload_size" transport parameter to limit
the size of the datagrams we want to receive.
