Ifc4x3 - entity-types mapping
- added mapping entity-types mapping based on iso release of ifc4x3 - added some manual corrections for `generate_util_type_json.py` if someone would regenerate the map for ifc4. - manual correction in ifc4x3 mapping for IfcCivilElement. It could be removed in the future releases of IFC if https://github.com/buildingSMART/IFC4.3.x-development/issues/583 is resolved If curious to look what were the changes for mapping between ifc4 and ifc4x3: https://github.com/IfcOpenShell/IfcOpenShell/commit/da51253fb0a9d08aa93f5fe3c074d3592b3aa997#diff-98f525c91bb47b9820e603fba61cc015d3e6ae7261593d727c51114e3ff73aa7
