usb hid: implement horizontal scrollwheel

Browse Source 
- Fix USB_hid_page_consumer.h: some values are skipped in the spec so
  our defines were off
- Handle the horizontal wheel on my mouse which is declared as a
  CON_AC_PAN, but otherwise works just like the vertical wheel
- Input server and interface kit already handle the events properly
  (they were available for serial mice already).
