QML: Pass the kind of geometry change around

This prevents re-calculation of what actually changed, and removes the
now unused parameter newGeometry. Other than this change calculation,
the only place where oldGeometry was used is
QQuickListViewPrivate::itemGeometryChanged. To get rid of oldGeometry
too, QQuickListViewPrivate now stores the current (i.e. last known)
geometry, and updates it in itemGeometryChanged.
