0026675: Eliminate normalization of coordinates in ApproxInt package

Normalization has been eliminated.

Additionally,
1. Some methods of AppDef_Compute and ApproxInt_MultiLine classes have become inline (for speeding up performance).
2. Interfaces of AppDef_Compute::Parametrization(...) and BRepAlgo_BooleanOperations::SetApproxParameters() methods have been changed.
3. Overloaded methods for ApproxInt_Approx::SetParameters(...), TopOpeBRepTool_GeomTool::GetTolerances(...) and TopOpeBRepTool_GeomTool::SetTolerances(...) have been removed (because some fields of these classes are not used more).
4. Lost comments have been added in BRepApprox_TheMultiLineOfApprox.hxx and GeomInt_TheMultiLineOfWLApprox.hxx files.
5. Some fields have been deleted from ApproxInt_MultiLine class. Kept members have become constant.
6. Interface of ksection DRAW-command has been changed.
7. Some code fragments have been rewritten to make them easier.
8. Function CleanWline(...) has been added in IntPatch_Intersection.cxx file. See comments in code for detail description.

Adjusting some test case according to their new behavior.
Creation test case for this issue.
