Send correct version negotiation to prober

QuicDispatcher::MaybeDispatchPacket was incorrectly computing the value of use_length_prefix instead of using the one from packet_info. This CL also adds regression tests to prevent this issue from coming back.

gfe-relnote: change length-prefix of version negotiation, protected by gfe2_reloadable_flag_quic_use_length_prefix_from_packet_info
