Initialize mGlobalSystemUiVisibility

ViewRootImpl doesn't pass System UI visibility change to children in ViewRootImpl.handleDispatchSystemUiVisibilityChanged() because there is no change in this case:
Reproduce steps :
1. fullscreen app in portrait (without statusbar and navigation bar)
2. switch to landscape (trigger recreating app in landscape mode)
3. slide down statusbar
Wrong Result : mView.dispatchSystemUiVisibilityChanged(visibility) was not called, so that app can't depend on the callback to refine its layout
This is because mGlobalSystemUiVisibility changed from some value to 0 (SYSTEM_UI_FLAG_VISIBLE)
