ifc5d: quantify IfcGeographicElement via EQto_GeographicElementBaseQuantities IfcOpenShell#6508

IfcGeographicElement has no base-quantity set in IFC4/IFC4.3 and no ifc5d rule,
so Perform Quantity Take-off reported it as not quantified. Add a Bonsai-custom
EQto_GeographicElementBaseQuantities rule (both IfcOpenShell and Blender engines,
IFC4 and IFC4X3) mirroring IfcSlab, computing Depth, GrossArea, NetArea,
GrossVolume, NetVolume and Perimeter.

Property set follows the maintainer wishlist from the thread (Depth, GrossArea,
GrossVolume, NetArea, NetVolume, Perimeter); Length and Width are omitted as not
standardisable for geographic elements.
