I am not sure if KeyboardOverlayDialog is the only dialog that should be
borderless on aura, therefore, I create a separate API
browser::CreateFramelessViewsWindow(). If we should make all dialogs with
STYLE_FLUSH to be borderless, then I can merge the code into
browser::CreateViewsWindow().

 // Create a bubble for a given |delegate|. Takes care of chromeos
 // specific window type setting if needed.
 views::Widget* CreateViewsBubble(views::BubbleDelegateView* delegate);
