Adapt to distutils being removed in 3.12

[nanonyme]

Creating an issue about this for tracking. 3.10 release notes mark distutils as deprecated and set a date for removal https://docs.python.org/3.10/whatsnew/3.10.html#distutils

This links to https://github.com/enthought/comtypes/issues/216 in a way that it might or might not be harder to keep supporting Python 2 once distutils is gone.

It would be good to work on this issue at the time of dropping Python 2.7 from support.

1.2.1 uses setuptools and supports both Python 3.12 and still Python 2.7. I think the issue can be closed.
