This is the last piece of gRFC A83 (https://github.com/grpc/proposal/pull/438).
Note that although this is the first use-case for this "blackboard" mechanism, we will also use it in the future for the xDS rate-limiting filter on the gRPC server side.

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.

Add a ValidateCredentials API to the TLS certificate provider interface. A user can call this API to check that the credentials currently held by the certificate provider instance are valid. The definition of "valid" depends on provider that is being used. For the static data and file watcher providers, "valid" means that the credentials consist of valid PEM.
~Currently there is no check to ensure that credentials consist of valid PEM blocks before a TLS handshake commences. This PR creates a static factory for FileWatcherCertificateProvider (and marks the constructor as deprecated) which performs this validation check. The analogous work for StaticDataCertificateProvider will be done in a follow-up PR.~

Some of our tests failed because RPC was canceled by server, error message:
```
I0000 00:00:1726598495.788119 64528 chttp2_transport.cc:1182] ipv4:127.0.0.1:41825: Got goaway [2] err=UNAVAILABLE:GOAWAY received; Error code: 2; Debug Text: Cancelling all calls {grpc_status:14, http2_error:2, created_time:"2024-09-17T18:41:35.78810597+00:00"}
```
It's possible that the request waited too long to be processed and thus canceled by server (default maximum time gRPC server allows a request to be received by the server but not handled is `30s`, controlled by `grpc.server_max_unrequested_time_in_server`).
This PR will print the test start/finish time so we know if we should increase `grpc.server_max_unrequested_time_in_server` time.

This is a retry of #37762 with a fix. We no longer hold the C mutex and GIL at the same to avoid a deadlock.
MetadataPluginCallCredentials passes a function pointer to C-core to be called during destruction. This function grabs GIL which may race between GIL destruction during process shutdown. Since GIL destruction happens after Python's exit handlers, we cana mark that Python is shutting down from an exit handler and don't grab GIL in this function afterwards using a C mutex.

Previously, if we pulled server trailing metadata *before* the call was added to the client transport then we'd never call `on_done_` on the spine and consequently never remove the call from the map. This change fixes that edge case.
In fixing it, I noticed a state in `CallState` that was both complicating the fix and completely irrelevant because we respecced earlier this year to say that ServerTrailingMetadata processing cannot be asynchronous, so I'm removing that state also.

It's possible for `LogStateChange` to be called after the party is destroyed (one thread calls Unref, which calls LogStateChange after the atomic op; another calls Unref concurrently, frees the last ref, deletes the object)
Consequently, it's not safe to call `DebugTag()` here - remove that.

Pretty sure that the `LoadBalancedCall` instance is getting dropped before return on *some* path through `PickSubchannel`, although it's unclear to me which and it's hard to tell with this implementation.
Ensure that such an event cannot cause a crash by holding a ref to the object we need and calling through that.
This will be marginally worse performance per pick for now, but once work serializer dispatch lands everywhere the additional ref will disappear.
