0026407: BRepMesh_Delaun should not take into account frontier edges on first pass of algorithm

Browse Source 
Correction of new vertices insertion: remove all triangles shot by point even if they contain frontier edges in order to prevent cases of free edge glued with frontier;
findNextPolygonLink: choose link with opposite direction to previous one as the last resort in case if the is no another option;
Enlarge bounding boxes by Precision::PConfusion() in order to not to miss possible intersections;

Test-case for issue #26407

Return NoIntersection in case of end point touch and isConsiderEndPointTouch flag is not set

Update of test-cases according to the new behavior
