Get rid of unused inputMethodQuery and inputMethodEvent functions in QQuickCanvas

* in Qt5 input method events and queries are meant to be sent directly to
  QInputPanel::inputItem() instead of the focused QWindow
* protected inputMethodEvent was actually never called by QWindow::event()
  like it called other specialized event functions
