Add fullscreen permission controls to settings

See http://crbug/378412 for details
This change adds fullscreen permission control to site settings.
For fullscreen, the settings has to be either ASK or ALLOW.
The settings behavior should match that of the desktop:
1. when a site enters fullscreen, an infobar will be shown to user if permission is not ALLOW.
2. The infobar will be dismissed when user click any button on it, or site leaves fullscreen.
