fuzz: update harness for ifcopenshell::file rename

Browse Source 
ifcviewer-wgpu renamed IfcParse::IfcFile to ifcopenshell::file (header
moved to ifcparse/file.h) and Base::toString to Base::to_string. Update
the harness and README to match; verified with a syntax-only compile
against this branch's headers.
