Move rebuildGeometry() functions of nodes

Move QSGDefaultImageNode::rebuildGeometry(),
QSGDefaultNinePatchNode::rebuildGeometry() to
QSGImageNode::rebuildGeometry(),
QSGNinePatchNode::rebuildGeometry()
respectively.

This makes it possible to use then from the D3D12 plugin
when built without OpenGL support.
