0024805: Eliminate unused static functions and methods: ShallowDump(), ShallowCopy(), STANDARD_TYPE(...)

Implementation of global functions STANDARD_TYPE() for types not inheriting Standard_Transient or Standard_Persistent are eliminated.

Global functions and class methods ShallowCopy() are removed; also removed unused classes Visual3d_PickPath and Visual3d_PickDescriptor.

Global functions and class methods ShallowDump() are removed, except for classes Standard_GUID, TopLoc_Datum, and TopLoc_Location as the latter are still used in some Debug printouts.
