Support LengthPrefixedConnectionIds in v99
This CL adds support for the invariants change from draft-22. It introduces a new parsing method QuicFramer::ParsePublicHeader which can parse both old and new formats, and uses it for v99 and also for all versions when gfe2_reloadable_flag_quic_use_parse_public_header is true.
gfe-relnote: change v99 encoding, protected by disabled v99 flag and by gfe2_reloadable_flag_quic_use_parse_public_header.
