quic: packet number encoding/decoding

QUIC packet numbers are integers in the range [0, 2^62).
Packet numbers are encoded as the 1-4 least significant bytes
of the full number, with the remaining bytes extrapolated based
on the largest packet number seen by the receiver.

RFC 9000, Section 17.1.

For golang/go#58547
