Explicitly announce the popup type when aria-haspopup is used

Notes:
* This will not be presented if the verbosity is set to brief.
* At the present time, no filtering of obvious or default types is
  taking place. (Example: The default popup of an ARIA combo box is
  "listbox". Rather than filtering it out, Orca will present it.
* The information is being tacked on to the very end of presentation
  so it can be interrupted by users who don't find it meaningful.
* What gets spoken when is subject to change based on user feedback.
