Compositor API: rename QWaylandInputDevice to QWaylandSeat

The name QWaylandInputDevice could be confusing and misleading:

- A QWaylandInputDevice was not one input device, but a collection of many.
- Classes that sounded like they should inherit from it did not, i.e:
  QWaylandKeyboard, QWaylandPointer and QWaylandTouch.
- The Wayland protocol already has another term for this, which is seat.
