Add dynamically-created Event Handlers to the relevant handlers vector
If any kind of Pointer Handler is created dynamically in JS by
calling Component.createObject(), QObject::setParent() is called
rather than passing the parent to the constructor, so
QQuickItemPrivate::data_append() did not take care of adding the
handler to QQuickItemPrivate's extra->pointerHandlers vector.
We need to use the auto-parent mechanism (just as we did with
handling dynamic creation of nested Windows in
8cb02e23abbefc9d020707fc1a2d8b6eb4e103b6). Added
QQuickItemPrivate::addPointerHandler() to put the prepend()
and implied setAcceptedMouseButtons() in one place.
Fixes: QTBUG-71427
