Make QuicSpdyStreamBodyBuffer manage consuming HEADERS frame header and payload.

Rename QuicSpdyStreamBodyBuffer::OnDataHeader(), update documentation, and rely
on it to calculate when HEADERS frame header and payload bytes need to be
consumed (but still call QuicStreamSequencer::MarkConsumed() from
QuicSpdyStream).  Rip out MaybeMarkHeadersBytesConsumed() and
headers_bytes_to_be_marked_consumed_ from QuicSpdyStream, which are hacky and
cannot be extended to take care of PUSH_PROMISE frames and unknown frames.

gfe-relnote: n/a, change to QUIC v99-only code.  Protected by existing disabled gfe2_reloadable_flag_quic_enable_version_99.
