Link IFC needs options for placement and rotation

We need Revit to handle different ways of placing the IFC upon linking.

Eg when the IFC is decided to be in true north, we are able to export it properly by exporting with surveypoint. This should also be possible on linking in.

The issue names no files or tests. Start by examining the Revit IFC linking flow and how survey-point and true-north placement are handled during export; clarify which placement and rotation options linking must support, then verify that linked models align as expected.
