Enable `jax` wheel testing via Bazel.
Remove jax dependencies from the Bazel test targets for `:build_jaxlib=false` and `:build_jaxlib=wheel`.
`internal_test_util` is removed from the `jax` wheel. To use this package in Bazel py_test, we need to copy it to the unpacked wheel folder. This is done by adding `wheel_deps` value to `py_import` Jax targets.
This change concludes ML Wheels design implementation in JAX and enables testing of all wheels via Bazel command.
