testing/openscad: fix CVE-2022-0496 & CVE-2022-0497
This does three things (each in its individual commit for easier reverting)
- testing/cgal: upgrade to 5.4
- testing/lib3mf: upgrade to 2.2.0
- testing/openscad:
- rebuild against the just updated cgal and lib3mf packages
- add secfixes from upstream commits as patches
- add compilation fixes with new cgal and boost from upstream commits as patches
