0028187: Add possibility to avoid creation of Internal parts in the result of Volume maker algorithm

1. The possibility to prevent addition of internal parts has been added into the following algorithms:
- BOPAlgo_BuilderFace;
- BOPAlgo_BuilderSolid;
- BOPAlgo_MakerVolume.

Setting the option to avoid internal parts for MakerVolume algorithm guarantees that the result solids
will be manifold and not contain any internal parts. But it does not prevent from occurrence
of the internal edges or vertices in the faces.

2. The Set/Get methods of the BOPAlgo_BuilderArea class have been made inline.

3. Draw command mkvolume has been updated to take into account the new option.

4. BRepOffset_MakeOffset::BuildShellsCompleteInter() has been modified to use the new option of BOPAlgo_MakerVolume
to speed up the construction of the final result solid.

5. Documentation has been updated with new section dedicated to BOPAlgo_MakerVolume algorithm.

6. Test case for the issue.
