[Android] Fix regression in binary size

It's introduced by M34 chromium, which include
unwind table for debug trace even for release build.
For chromium case, the debug info will only be
excluded for official build.

Fix this by explicitly disable unwind table for
release build.

TODO: Revert this patch after crosswalk supports
official build also.

Introduce "--fullscreen" command line option for xwalk-launcher

Introduce "--fullscreen" command line option for xwalk-launcher
in order to allow launching applications in fullscreen mode
without necessity to re-start xwalk service process. Besides,
it allows simultaneous running applications in both fullscreen
and default modes.

This patch also moves the logic enabling fullscreen mode from the
Runtime class to more appropriate places: ApplicationSystem
and RunningApplicationsManager.
