PathView: stop using QQWindowPriv::cloneMouseEvent; refactor filtering

There's no need to heap-allocate a short-term mouse event; and
localizing one is easy enough via QMutableEventPoint::setPosition.
The sendMouseEvent() function (and its name) didn't make as much sense
as handling the filtering completely in the childMouseEventFilter()
function.  Checking and changing the grabber is also now possible via
accessors in the event itself, so now we have one fewer use of
QQuickItem::grabMouse() and QQuickWindow::mouseGrabberItem().
