This PR adds templating for Python versions and updates the maximum supported Python version to 3.13. The following major changes related to templating are added:
- Minimum supported Python version and list of supported versions in `setup.py` are fetched using new template generated files called `python_version.py`
- Dockerfiles for the different Python Linux builds are now template generated.
- The "Supported Python Versions" section from READMEs of ancillary and main packages have been removed
Note: All the `python_version.py` files and Linux build `Dockerfiles` except `tools/dockerfile/grpc_artifact_python_linux_armv7/Dockerfile` in the PR are generated from the respective templates.
Further non-templated additions to add support for Python 3.13:
- install scripts and artifacts for windows, macos and linux are added manually. Later, these can be templated as well.
- updated cython bounds to 3.x
- updated twine version to solve [cgi module import error](https://github.com/pypa/twine/issues/1046)
- the twine update introduces a dependency on cryptography>=2.0. But the cryptography package doesn't support 32-bit Linux images and hence `twine check` has been disabled for x86 manylinux and x86 musllinux artifacts.
Closes#37643

Fix incompatibilities identified when running adhoc runs on the new
custom win2019 image.
After merging this, it should be possible to switch to the new image
without breaking any tests.
- for most fixes I added a comment that explains why they're necessary.
- the new image won't have VS2015 installed, so I'm switching the protoc
artifact build to VS2017
This PR will need to be backported to older release branches to ensure
the windows tests continue working on those branches as well (IMHO I
haven't made any changes that would be difficult to backport and I tried
to keeps the diff as small as possible to avoid issues when
backporting).
After we switch to the new image (and all the windows tests are green),
we can incrementally move the builds that are still using VS2017 to
VS2019.
