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

Add a step in distribution test which checks if any of the artifacts exceeds 80 MB since Pypi has a per-file size limit.

Change was created by the release automation script. See go/grpc-release.
On top of changes made by the script, `setup.py` had to be updated to have `/std:c11` option for MSVC to use c11 features for boringssl.

* support "move and respawn" for kokoro jobs
* delete_nonartifacts.sh no longer needed
* bazel distribtest dont publish any artifacts
* try the altsrc respawn for selected jobs
* use altsrc for all windows CI jobs
* use altsrc for all macos CI jobs
* only move files under src/github
* fix uploading artifacts on windows
The source code is moved from src/python to
src/python/src. A setup.py is added at
src/python. The build_python.sh and
run_python.sh scripts are updated to build
and run the Python tests by building a
package and installing it in the developer's
Python 2.7 virtual environment.
