[llvm] Replace distutils.version with packaging.version since the former was deprecated in python 3.10 and removed in 3.12. (PR #99852)

[via llvm-commits]

https://github.com/dyung created https://github.com/llvm/llvm-project/pull/99852

Attempt to reland #99549, but using packaging.version instead of looseversion, based on the usage used for LLDB in #93712.

@JDevlieghere and @mysterymath I believe this should already be fine for your bots because you already have the packaging package installed for LLDB correct?

@tlively I used this attempt to reland the change to restructure it as was suggested in #99549 to limit the scope of the import until it is needed.

I have tested this manually on both of my cross-project-test bots, and both pass once I installed the packaging package.
