PR: Parameter Export Mapping

### Problem Description

I'm trying to use the following export mapping to have the nominal dimensions of pipe and duct segments in the appropriate psets, as per the Autodesk IFC Handbook.
```
Pset_DuctSegmentTypeCommon NominalDiameterOrWidth Diameter
Pset_DuctSegmentTypeCommon NominalDiameterOrWidth Width
Pset_DuctSegmentTypeCommon NominalHeight Height
Pset_PipeSegmentCommon NominalDiameter Diameter
Pset_PipeSegmentCommon WallThickness Wall Thickness
```

Unfortunately this doesn't work, these properties are still not exported. I'm using IFC4. Are there any limitations that should be considered?

### Revit Version

2024.3.x

### IFC for Revit Addon Version

24.3.2

### Windows Version

11 24H2

Start by reproducing the export mapping with Revit 2024.3.x, IFC for Revit 24.3.2, and IFC4, using the pipe and duct mappings shown in the issue. Inspect the parameter-export path and compare the generated property sets with the Autodesk IFC Handbook. Done means determining whether these mappings are supported and documenting the applicable limitation or expected behavior.
