0028470: Foundation Classes, NCollection_Array1 - add Resize() method for re-allocating array with new limits

NCollection_Array1 now provides method Resize() for re-allocating array to new bounds.
Added Move Constructor and Move Assignment operator.
Added empty constructor defining array of zero size.

#Poly_Triangulation, dropped duplicating fields myNbNodes and myNbTriangles.
#Removed unused file Poly_Triangulation.lxx.
