0028501: Incomplete result of offset operation in mode Complete with Join type intersection

1. The algorithm BOPAlgo_ShellSplitter has been improved for the cases with multi-connected edges
to produce as many shells as possible from the given input faces.

2. Building tool prism in BRepFeat_MakePrism has been changed in order to avoid self-intersections
in the cases when the limiting faces are intersecting.

3. Test cases for the issue.

4. Test cases boolean/bcut_complex/N9 and boolean/gdml_private/ZH3 are improvements.

5. Test cases boolean/volumemaker/C5 and boolean/volumemaker/C6 has been marked as BAD due to found problem in intersection algorithm.
The results in these cases obtained on the branch are better than on master, but still not complete.

Adjusting test case bugs/moddata_2/bug469 for its current behavior.
