Do not send PRIORITY_UPDATE from server.

While https://httpwg.org/http-extensions/draft-ietf-httpbis-priority.html allows
servers to send PRIORITY_UPDATE frames, there is currently no need for this
feature.  Note that clients are already ignoring incoming PRIORITY_UPDATE frames
in QuicSpdySession::OnPriorityUpdateForRequestStream().

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