This ticket renames affine_hull of Polyhedron_base to in_affine_hull and adds a deprecation warning.

Before, this function was hard to find, as an affine hull of a polyhedron usually defined to be the smallest affine subspace containing the polyhedron.

Also this ticket makes use of #28724 to simplify this construction: We determine a transformation matrix A and a vector b and basically return A*P - b, where P is the polyhedron.
