PR: not able to export built in material parameters into standardised IFC psets

### Problem Description

There are two ways material psets come out:

1. https://github.com/Autodesk/revit-ifc/blob/b83595ff01f72f2a63242e00daf01508f2264287/Source/Revit.IFC.Export/Utility/MaterialPropertiesUtil.cs#L56-L58 from built-in parameters into hardcoded property sets called things like "Identity" or "Structural".
2. https://github.com/Autodesk/revit-ifc/blob/b83595ff01f72f2a63242e00daf01508f2264287/Source/Revit.IFC.Export/Utility/MaterialPropertiesUtil.cs#L60 using a custom mapping from custom project / shared parameters where you can use the user defined psets txt config file to put it in whatever Pset you want.

The problem is that the first way does not put data into standard bSI psets. So the Revit built-in concrete compression data goes into a pset called "Structural", not "Pset_MaterialConcrete". And the second way cannot map these "built-in parameters" to my knowledge.

So my possible workarounds are to 1. patch the IFC to put it in the right spot and delete the other parameters that don't interest me / aren't validated or 2. create another project parameter and have the data duplicated in two spots.

Start in Source/Revit.IFC.Export/Utility/MaterialPropertiesUtil.cs, especially the built-in parameter handling around lines 56-58 and custom mapping around line 60. Trace how built-in material parameters are assigned to exported property sets. Done means built-in concrete compression data and other applicable material parameters can be placed in the corresponding standard bSI property sets rather than only hardcoded sets such as "Structural".
