refactor(pypi): parse entry_points without Python (#3429)

This is a small utility function to get us Python free when wheels are
extracted in the repository phase.

Next is to extract the wheel using `repository_ctx.extract` (#3430).

Whereas patching the wheel after extracting is more involved to be done
without Python because we need to rezip the wheel and that has to be
done
with Python for a few reasons (to stay sane). If we want to remove this,
then we would have to create a `whl` file in the build phase, which
could
work, but will need to be an exercise for the reader.

Nevertheless, this moves us towards removing any side-effects from
Python
interpreter, so changing the default interpreter would not cause us to
refetch everything.

Python Rules for Bazel

Build status

Overview

This repository is the home of the core Python rules -- py_library, py_binary, py_test, py_proto_library, and related symbols that provide the basis for Python support in Bazel. It also contains package installation rules for integrating with PyPI and other indices.

Documentation for rules_python is at https://rules-python.readthedocs.io and in the Bazel Build Encyclopedia.

Examples live in the examples directory.

The core rules are stable. Their implementation is subject to Bazel's backward compatibility policy. This repository aims to follow semantic versioning.

The Bazel community maintains this repository. Neither Google nor the Bazel team provides support for the code. However, this repository is part of the test suite used to vet new Bazel releases. See How to contribute page for information on our development workflow.
