--[WIP][BE/Refactor/Bugfix] Remove deprecated distutils from setup and ab_test

[jturner65]

Motivation and Context

Distutils is deprecated and will be removed in python 3.12, which is slated for release Oct 2 2023. This PR removes references to Distutils in HabitatSim python code. It does require the 'packaging' library, so this also needs to be added to requirements.txt. (@Skylion007 is there a better option than this to provide version classes?)

NOTE : Our versions of bullet, assimp and pybind11 all also have distutils references, so we may need to update these libraries before we can claim python 3.12 support. (magnum also does, but I'm sure mosra will address when appropriate).

We should probably also bump the supported versions for our conda builds.

Latest version of pybind11 supports python 3.12. Also latest versions of torch will too now.
