Python wheels for module and ogs binaries

• Add CI jobs which build portable Python wheels of OGS
• The wheel contains the OGS Python module developed for model coupling (import ogs.simulator) and the OGS binaries
  • Once the wheels are uploaded to PyPI (upon the next OGS release) you can install OGS simply by running pip install ogs
  • Right now you can install via test.pypi.org: pip install -i https://test.pypi.org/simple/ ogs
  • Python 3.8 - 3.11 supported
• The configuration ogs inside the wheel has the following configuration:
  • All processes (except of TH2M on Windows)
  • MFront support
  • No Python boundary conditions support (currently not possible as the build environment for the portable wheels does not include libpythonX.Y.so which is required for OGS_USE_PYTHON=ON, see also PEP 513)
