Separate wheel building and testing

[SaillantNicolas]

the wheel test is now in another job.

That creates a nice drawing of the graph of jobs, at https://github.com/CGAL/cgal-swig-bindings/actions/runs/7627051759?pr=262

The Github actions will fail on Windows and MacOS, because of the upgrade to SWIG 4.2. @sloriot might come up with a proposal for a fix, eventually.

@SaillantNicolas:

I have fixed the CI in main (#263), and merge back main here. And also two improvements: 86efe52 and d210b99.

Now there are two issues:

• on Windows, the expected failure of the test of the wheels (because TBB is not shipped),
• on macOS, an incomprehensible error ERROR: cgal-5.6.post202401251314-cp39-cp39-macosx_10_9_x86_64.whl is not a supported wheel on this platform. There are probably several version of Python installed, and the wrong one is picked (note that Test Wheel (master, 3.12, macos-latest) does not fail, probably because the system Python is version 3.12).

On Windows, we should use https://pypi.org/project/delvewheel/ to "fix" the wheel (like auditwheel on Linux and delocate on macOS).

Or maybe use https://github.com/jvolkman/repairwheel on all three platforms.
