Add crosswalk for Tizen IVI support.

1 Add the follow capabilities tizenDebuggerAddress, tizenAppId, tizenAppName
  and tizenDeviceSerial. The tizenDebuggerAddress is necessary. The others are
  pre-reserved, has no practical effect.
2 On Tizen IVI, the sdb command can not launch xwalk remotelly. So need to
  launch the xwalk manully.
