Handle the basic logic to show or hide accessibility floating menu

* AccessibilityFloatingMenuController will listen to the changes from AccessibilityButtonTargetsObserver and AccessibilityButtonModeObserver then handle the visibility of FloatingMenu
* Add abstract class SecureSettingsContentObserver to handle a registry of listeners of specific types and dispatch changes to child
