This adds a new `Transform` output socket of matrix type to the Object Info node.
This is clearly useful, but we did not do this before for a couple of reasons:
* It's redundant with the location, rotation and scale outputs.
* We might want separate `Object Transform` and `Object Geometry` nodes.
For now just adding the socket is probably useful enough to justify it. Even more
so because it's addition doesn't really block other designs in the future either.
