Change default QuicStream priority when using IETF QUIC.

This allows removal of MaybeSendPriorityUpdateFrame() call in
QuicSpdyStream::WriteHeaders(): if priority is default, no need to send
PRIORITY_UPDATE; if SetPriority() has been called, then PRIORITY_UPDATE has
already been sent.

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