Summary0022505: BRepMesh produces triangulation with free nodes
DescriptionThis bug was a root-case for bug OCC22503: triangulation of the face contains
some free nodes (not shared by any triangle).

Though seems to not cause severe problems after OCC22503 is fixed, such
triangulations are not valid and the algorithm should be fixed.

The attched face allows to reproduce the problem in OCCT6.4.0 or OCCT6.5.1rc1 +
OCC22318. It is not reproduced on OCCT 6.5.0 and pure OCCT 6.5.1 rc1.

Steps to reproduce (assuming that new features in command "checktopo"
introduced in OCC22503 are available):
