add variant of PMP::self_intersections using AABB_tree

[LeoValque]

Summary of Changes

Add a parallellization of AABB_tree::build() (without any mutex) to improve running time.

Add PMP::AABB_self_intersections(), a variant of PMP::self_intersections() that used an AABB_tree instead of CGAL::box_intersection_d.
