PMP::isotropic_remeshing() - add NP `allow move functor`

[janetournois]

Summary of Changes

The function tangential_relaxation() has a named parameter called allow_move_functor that enables the user to prevent and cancel some vertex moves.

With this PR, it is now possible to use the same parameter for the relaxation steps of CGAL::Polygon_mesh_processing::isotropic_remeshing()

To solve #8134, we can think of a smart functor that would prevent self-intersections from being introduced by the relaxation step

To solve #8134, we can think of a smart functor that would prevent self-intersections from being introduced by the relaxation step

Should we close the issue #8134, how that this PR is merged, or leave it open? Because it seems the actual solution to #8134 is

• this PR #8150,
• plus something else (see the quote above).

I will post a possible functor in the issue soon! Thanks for assigning it to me
