This PR enables Python 3.14 in all the different tests - Basic tests (Native Python tests), Bazel tests and Distrib tests to build Python 3.14 artifacts. In addition, it also updates all the public facing METADATA versions. ## Distribtests Required pre-requisite changes to enable 3.14 artifacts are covered in #40289 . ## Bazel tests Enabling Python 3.14 required updating the rules_python version to a more recent version that supports 3.14. This was done in #40602 ## Basic tests The following errors were caught by the Basic tests when running via Python 3.14 and resolved in this PR: ### 1) No running event loop for AsyncIO when run outside an async function ``` Traceback (most recent call last): File "src/python/grpcio/grpc/_cython/_cygrpc/aio/common.pyx.pxi", line 184, in grpc._cython.cygrpc.get_working_loop RuntimeError: no running event loop ``` This was caught by the `tests_aio.unit.outside_init_test.TestOutsideInit` and `tests_aio.unit.init_test.TestInit` tests, and was also previously reported in #39507 with the root cause. Following some investigation, the fix is being worked on by @sergiitk in PR #40293. In order to parallelize the fix and this PR, these 2 tests are currently being skipped for Python 3.14 and above. ### 2) Pickling error from the `multiprocessing` library ``` _pickle.PicklingError: Can't pickle <function _test_well_known_types at 0x7f3937eee610>: it's not the same object as tests.unit._dynamic_stubs_test._test_well_known_types when serializing dict item '_target' when serializing multiprocessing.context.Process state when serializing multiprocessing.context.Process object ``` This was caught by the `tests.unit._dynamic_stubs_test.DynamicStubTest` which runs test cases in a subprocess using the `multiprocessing` library. Error root cause: - The default start method of multiprocessing in linux has changed to `forkserver` instead of `fork` from Python 3.14. - `forkserver` has a few extra restrictions for picklability as compared to `fork` (Ref: [Python Docs](https://docs.python.org/3.14/library/multiprocessing.html#the-spawn-and-forkserver-start-methods)) - All the [test case functions](https://github.com/grpc/grpc/blob/0243842d5d10f624bf8f09f45026dd300805502f/src/python/grpcio_tests/tests/unit/_dynamic_stubs_test.py#L115) in the DynamicStubTest that are provided as `target` to the `multiprocessing.Process` use decorators. This causes problems when pickling them. Hence to resolve this, we manually set the 'start method' of `multiprocessing` to use the `fork` start method. Closes #40403 PiperOrigin-RevId: 804290760
