CI: move test_numpy_main to linux_meson

[tupui]

Follow up of #16739

I am not sure about 2 things:

1. do we want the maintenance skip (if: "github.repository == 'scipy/scipy' && !contains(github.ref, 'maintenance/') && !contains(github.base_ref, 'maintenance/')"). I think this is a leftover as we have the on: push: branches specification.
2. do we really need setuptools==59.8.0 wheel in the 3.9 job??

@rgommers CI is green. LMK if there is anything to adapt here.

We do need this. The first part is: "don't run on forks" (not a leftover, wanted in all jobs). The second part is "don't run the testing against main branches of dependencies in maintenance branches". That tends to fail and we disabled it on purpose.

There's one issue here now though: since you mixed this job with the 3.9 job, we cannot easily disable just one of these.

2. do we really need setuptools==59.8.0 wheel in the 3.9 job??

It looks like that is a leftover indeed, can you remove it?

Yes I was referring to the second part only. I can just make a second conditional clause to skip if 3.11 & maintenance.

Looks like the added job is not running. You probably should iterate on this in a PR to your own fork. The way I do that is add a single WIP commit, changing main to the name of the branch I'm working in and scipy/scipy in the skip condition to rgommers/scipy; that way only the job you are working on will run.

[tupui]

After some googling, this happens because the matrix part cannot be used at that point. Apparently I could use exclude to do this. I will try on my fork if you prefer then.

[tupui]

Ok I think I got it with exclusion pattern and it's easier to read IMO. See tupui#8 and tupui#9 to see it in action.

The Mypy step isn't erroring out when it should:

Installation OK
scipy/integrate/setup.py:4: error: Cannot find implementation or library stub for module named "scipy._build_utils"  [import]
scipy/integrate/setup.py:4: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports
scipy/integrate/setup.py:9: error: Cannot find implementation or library stub for module named "scipy._build_utils.system_info"  [import]
scipy/stats/_hypotests.py:14: error: Cannot find implementation or library stub for module named "scipy.stats._hypotests_pythran"  [import]
Found 3 errors in 2 files (checked 783 source files)

That is already happening in main though, so let's ignore it here. I can reproduce it locally as well. I'll send a separate fix for that.

LGTM, thanks @tupui!
