QWaylandClient - setInputMethodHints() doesn't work with QtTextInputMethodManager

We make use of an Qt ivi wayland compositor and Qt 5.12.11.
and integrated the patch of QTBUG-85554 and https://codereview.qt-project.org/c/qt/qtwayland/+/311730.

The issues are reproducable on both

• Snapdragon 820A development board running Linux and Wayland 1.9
• Ubuntu 20 and Wayland 1.16

Observed issue:

• When the WaylandClient sets a inputMethodHint. It is not considered by the Compositor/Keyboard. e.g.

  setInputMethodHints(Qt::ImhDialableCharactersOnly)
  

When using the inputMethod: TextInputManager it is working fine. When using QtTextInputMethodManager the request is ignored.
