Show an a11y notification only if the feature was enabled by its shortcut key
Currently, only spoken feedback has a shortcut key, so this CL supports only it.
Major Changes:
- Add a |notify| argument to ToggleSpokenFeedback() methods to pass the flag whether the tray should show a notification or not.
- (in ash_system_tray_delegate.cc) Use chrome notifications instead of watching pref change to observe the accessibility feature status change.
