Python module `distutils` is deprecated, consider replacing it

[stevapple]

lldb/bindings/python/prepare_binding_python.py imports distutils which used to be a part of Python standard libraries, but was deprecated long ago and finally removed in Python 3.12. Thus we'll get the following error if we tried to build with a vallina Python 3.12 install:

We should consider replacing it with a modernized module, though they're most likely not included in the standard libraries

FYI Upstream LLVM's choice was packaging.
