0025617: Avoid classes with a copy constructor and the default destructor or assignment operator

Removed useless user-defined copy constructors and assignment operators in BOPCol_NCVector, NCollection_Mat4, NCollection_Vec*

User-defined assignment operator matching copy constructor added in NCollection_StdAllocator.

Class VrmlData_DataMapOfShapeAppearance redefined as simple typedef to NCollection_DataMap<>.
