fix(build): update mojo files for python 3.12

This allows compilation of the mojo project with python 3.12.
* Replace `imp` module with the newer `importlib.util` module that was added in 3.4.
* This allowed for successful builds on my test machines (windows and linux),
* Some reports say that `setuptools` or `distutils` was still missing and is needed to build the natives, I wasn't able to replicate this.

Note: setuptools can can installed as follows: `pip install setuptools` or `py -3 -m pip install setuptools`
