This change enables testing the wheels produced by the build rules in the presubmit using one `bazel test` command only.
There are three options for running the tests:
1) `build_jaxlib=true`: the tests depend on JAX targets.
2) `build_jaxlib=false`: the tests depend on the wheel files located in the `dist` folder.
3) `build_jaxlib=wheel`: the tests depend on the py_import targets.

This change introduces a uniform way of building the artifacts and controlling the filename version suffixes (see the changes for `jaxlib`, `jax-cuda-plugin` and `jax-cuda-pjrt` in https://github.com/jax-ml/jax/pull/25126)
Previously `jax` wheel was built via `python3 -m build` command. The resulting wheel contained the python packages files in `jax` folder (e.g. the files in the subdirs that have `__init__.py` file).
You can still build the `jax` wheel with `python3 -m build` command.
Bazel `jax` wheel target: `//:jax_wheel`
Environment variables combinations for creating wheels with different versions:
* self-built wheel (default build rule behavior): `--repo_env=ML_WHEEL_TYPE=snapshot`
* release: `--repo_env=ML_WHEEL_TYPE=release`
* release candidate: `--repo_env=ML_WHEEL_TYPE=release --repo_env=ML_WHEEL_VERSION_SUFFIX=-rc1`
* nightly build: `--repo_env=ML_WHEEL_TYPE=custom --repo_env=ML_WHEEL_BUILD_DATE=<YYYYmmdd> --repo_env=ML_WHEEL_GIT_HASH=$(git rev-parse HEAD)`

This PR depends on https://github.com/openxla/xla/pull/17169. The change does not fail existing builds, but to be able to use python 3.13 functionality in jax the corresponding XLA pr needs to land first and get integrated with JAX (happens automatically).
