quic: pass the connection ID length into 1-RTT packet parsing

1-RTT packets contain a variable-length connection ID field, but
no indication of the length of the connection ID.  The recipient
of the packet has chosen the connection ID, and is expected to
either choose a consistent length or encode the length in the
connection ID.

Change the parse1RTTPacket function to take the connection ID
length as an input, rather than assuming that all 1-RTT packets
contain our hardcoded connection ID length.

This permits using parse1RTTPacket in tests which may create
and parse packets using other lengths.

For golang/go#58547
