OMPython breaks with Python 3.12

[JaxRaffnix]

Description

OMPython is not compatible with python 3.12 because distutils is deprecated. See 1 for details.

OMPython imports spawn from distutils and uses the find_executable() function for the class OMCSessionHelper.

Steps to reproduce

Install OpenModelica and Python 3.12. Install OMPython with this guide 2. Execute a test script:

from OMPython import OMCSessionZMQ
omc = OMCSessionZMQ()`

Expected behavior

Change the function find_executable() with the recommended subprocess.run().

@JaxRaffnix I suggest you to manually setup the install after downloading the OMPython repo and do

>>> python setup.py install

It's not good when OMPython isn't running out of the box on Python 3.12 and newer.
I encountered this in some CI I'm creating. setup.py isn't easily available when installing OMPython via pip.

@arun3688 we should move towards setuptools.
