Asking for a C++ counterpart for QML TouchPoint

Currently in Qt6, the QEventPoint cannot be constructed with position relative to event receiver (the 'local' position instead of scene or global position). Nor there is setter for position since position is read-only. Thus, a customer requires something like QTouchEvent::ToucPoint in Qt5 to be available in Qt6 so that touch point can be shared seamlessly between QML and C++.
