[Tizen IVI] Hide title bar in fullscreen mode.

Currently, Crosswalk for Ozone-wayland shows title bar by default
on Tizen IVI. As a result, when webapps enter fullscreen mode using
HTML5 fullscreen API, their title bar still exists.

This patch allows to hide title bar in fullscreen mode.

It depends on the following commit in chromium-crosswalk:
