0025616: Avoid Classes using "new" to allocate Instances but not defining a copy Constructor

The empty copy constructor, assignemnts operator, default constructors added to the following classes:
The following classes use “new” function without Handles:
- Select3D_PointData
- BSB_T3Bits
- IntPatch_InfoPD
- LDOM_StringElem
- BinomAllocator
- ProjLib_OnSurface
- Standard_MMgrFactory

Useless declaration of default constructor have been deleted.
