        Note on selected/unselected icons:
        The icon is always tinted with @color/car_nav_icon_fill_color_selected in @layout/car_system_bar_button
        Unselected: keep this behavior so all icons have consistent color (eg. tint a multi-colored default app icon)
        Selected: set selected alpha 0, making icon transparent. Use state list nav_bar_button_background to show selected icon (in addition to background).
