Add PointerHandler.cursorShape property
Also, QQuickItemPrivate::setHasCursorInChild() was unable to check
the QQuickItemPrivate::hasCursor variable, because the function
argument hasCursor was shadowing that, even though the comment
"nope! sorry, I have a cursor myself" hints that the intention
was to check that. So this change exposed a problem there, and
we have to fix that too, in order to keep the tst_qquickwindow::cursor()
test passing.
[ChangeLog][Event Handlers] Pointer Handlers now have a cursorShape
property to set the cursor when the handler is active and the mouse is
hovering, and restore to the previous cursor when the mouse leaves.
Fixes: QTBUG-68073
