[QTBUG-27308][QTBUG-21534] Don't mouse-wheel-scroll QScrollBar when disabled
This fixes a regression introduced in Qt 4 commit e855b199319c932f2e9500235775f961bc32e41a. The problem was that by handling the wheel event in event() instead of wheelEvent(), we lack the guard clause in QWidget that doesn't even call the handler if the widget is disabled, and the code didn't handle this itself. Fix by reimplementing wheelEvent() instead, which we can now do because we can break BC. This commit just moves the code. Another commit will clean up the implementation of wheelEvent().
