QQuickDeliveryAgentPrivate::pointerTargets: omit subscene root children

When we ask for the delivery target items in the window's contentItem,
the list should NOT include any item that is a subscene root (nor its
children), because delivery to those is done later in
QQuick3DViewport::internalPick() by calling QQuickDeliveryAgent::event()
on the subscene agent. It's premature for the main DA to deliver events
there (except in the case that it delivers an update event to a grabber,
which doesn't involve calling pointerTargets() anyway).

As for why the subscene root is a child of the window, even when it's
only being used as a texture source, that's from qtquick3d
