Summary0032717: Modeling Algorithms - BRepBuilderAPI_Copy should not remove triangulation from surface-less faces
DescriptionBRepBuilderAPI_Copy::Perform() has a flag `copyMesh` intended to avoid copying of triangulation in addition to geometry.
In case of triangulation-only geometry this operation produces an invalid empty faces, which makes no sense.

It is proposed ignoring this flag in such cases, similar to BRepTools::Clean().
Steps To Reproduce
pload XDE MODELING
box b 1 2 3
incmesh b 1
checktrinfo b -tri 12 -nod 24
tclean -geom b
trinfo b
checktrinfo b -tri 12 -nod 24

tcopy b bb
trinfo bb
checktrinfo bb -tri 12 -nod 24
# KO - copied shape is empty
