[IFC Tunnel] Add predefined types for IfcBorehole and change base type and deprecate old unused base types

Predefined types:
- COREDRILLING : A drilling process in which borehole is performed by cutting out cylindrical rock or soil samples in the field, using a core barrel.
- DESTRUCTIVEDRILLING : A drilling process in which the boring is performed using destructive tools
- TRIALPIT : An excavation made for the purpose of observing shallow subsurface conditions, performing field tests and obtaining soil samples.
- SUBTYPE OF IfcGeoScienceElement
WHERE
- CorrectPredefinedType : NOT(EXISTS(PredefinedType)) OR
(PredefinedType <> IfcBoreholeTypeEnum.USERDEFINED) OR
((PredefinedType = IfcBeamTypeEnum.USERDEFINED) AND EXISTS (SELF\IfcObject.ObjectType));

Please note that IfcGeotechnicalAssembly, IfcGeoSlice and IfcGeoModel shall be deprecated

Start by reviewing the IFC schema definitions for IfcBorehole and the listed base types. Check how predefined types, inheritance, and WHERE rules are represented, then verify that the requested deprecations and base-type change are reflected in the generated specification documentation.
