Remove IETF QUIC Application Close frame, replace with Connection Close

This CL removes the IETF QUIC Application Close frame and replaces it with the Connection Close frame.  QuicConnectionCloseFrame::close_type indicates whether the frame is a Google QUIC Connection Close, IETF QUIC Connection Close/Transport or IETF QUIC Connection Close/Application.

The QuicFramer::...ApplicationCloseFrame... methods are removed.

gfe-relnote: N/A affects only IETF-QUIC/V99 code. Application Close was IETF-QUIC only.
