MAINT: Raise RuntimeError if setuptools version is too recent.

NumPy does not build with setuptools versions greater than '60.0.0'.
Check the version when setuptools is imported in setup.py and raise
a RuntimeError if the version is too recent. That way we avoid people
opening issues when their build fails for that reason.

Closes numpy#20692.
