[TM19] Excavation

[aothms]

Description: "Introduced excavations semantic objects, added abstract parent of IfcEarthworksCut."

Scope: "ENTITY IfcExcavation, ENTITY IfcFaceExcavation, ENTITY IfcRadialExcavation, ENTITY IfcUndergroundExcavation, TYPE IfcFaceExcavationTypeEnum, TYPE IfcRadialExcavationTypeEnum"

Notes: IfcEarthworksCut re-parented from IfcFeatureElementSubtraction to IfcExcavation to reflect the new hierarchy.

Editorial commits: PEnum values harmonized per integration convention: tail normalized to OTHER/NOTKNOWN/UNSET, compound literals renamed to follow naming convention (e.g. DRILLANDBLAST → DRILL_AND_BLAST).
