0025622: CAST analysis: Avoid invocation of virtual Methods of the declared Class in a Constructor or Destructor

The Delete() methods have been deleted from the following classes:
- Adaptor2d_Curve2d
- Adaptor3d_Curve
- Adaptor3d_Surface
- AppBlend_Approx
- AppCont_Function
- AppParCurves_MultiCurve
- AppParCurves_MultiPoint
- ApproxInt_SvSurfaces
- BRepPrim_OneAxis
- BRepSweep_NumLinearRegularSweep
- BRepSweep_Translation
- BRepSweep_Trsf
- DBC_BaseArray
- GeomFill_Profiler
- HatchGen_PointOnHatching
- math_BFGS
- math_FunctionSet
- math_FunctionSetRoot
- math_FunctionWithDerivative
- math_MultipleVarFunction
- math_MultipleVarFunctionWithHessian
- math_MultipleVarFunctionWithGradient
- math_Powell
- math_NewtonMinimum
- math_NewtonFunctionSetRoot
- math_BissecNewton (just add virtual destructor)
- math_FRPR
- math_BrentMinimum (just add virtual destructor)
- OSD_Chronometer
- ProjLib_Projector

Virtual methods Delete() or Destroy() of the transient inheritors is not changed (-> separate issue).
Classes Graphic3d_DataStructureManager and PrsMgr_Presentation without changes.
