Add frame header and payload length argument to HttpDecoder::Visitor::OnHeadersFrameStart().

QuicSpdyStream, a HttpDecoder::Visitor implementation, needs to know the HEADERS
frame length in order to call SpdyStreamSequencer::MarkConsumed() when
appropriate.  This CL is chipped off of the draft CL at cr/231494986.

gfe-relnote: n/a.  Change in QUIC v99 only.
