AABB_tree: Circle_2/Iso_rectangle_2 intersection with inclusion

[soesau]

Issue Details

The AABB_tree with 2D primitives uses its own do_intersect_circle_iso_rectangle_2 which considers inclusion as intersection while the corresponding function in Intersection_2 does not. The AABB_tree with 3D primitives also uses a static filter for some optimization which would also be helpful in the 2D variant.

#8891 created the internal do_intersect_circle_iso_rectangle_2 in AABB_traits_2, which provides correct closest_point results.
