* Allows to check whether accessibility means are in use (Narrator/3rd party tools on Windows, VoiceOver on macOS)
* Adds Accessible.MakeAnnouncement (string message, bool polite = false) method for making a custom announcement for user per request (uses LiveRegion on Windows and NSAccessibility.PostNotification on macOS)
