Split BasePrimitive2D UNO interface into separate object

Rather than make all the BasePrimitive2D classes bear the cost of being an UNO
object, we just wrap the top level BasePrimitive2D in this class when we need
to pass them over UNO.

This reduces the locking overhead when doing normal drawinglayer operations,
and reduces the size of drawinglayer objects and the cost of initialising
them, which shaves 5% off the load/display time of a large barchart.

Add new drawinglayer::convertPrimitive2DContainerToBitmapEx utility
method to avoid needing to convert to Sequence<XPrimitive2D>
