Replace distutils.version with looseversion since the former was deprecated in python 3.10 and removed in 3.12. (#99549)

Python deprecated the distutils package in 3.10, and removed it in 3.12
causing problems when trying to run the lit tests with 3.12.

https://docs.python.org/3.10/library/distutils.html

Replace usage with the looseversion package which should be a drop-in
replacement for the original usage.

If your testing fails after this commit, you need to install the looseversion package.
