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

[via llvm-commits]

https://github.com/dyung created https://github.com/llvm/llvm-project/pull/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.
