First check-in of configuration overhead measurement tool

i.e. first check-in of [Measuring Configuration Overhead](https://docs.google.com/document/d/10ZxO2wZdKJATnYBqAm22xT1k5r4Vp6QX96TkqSUIhs0/edit).

This just establishes supporting structure. The tool is not yet functional.

Specifically:
- `types.py`: defines data structures for "configuration" and "configured target"
- `bazel_api.py`: API to translate `bazel cquery` and `bazel config` calls into the above data structures
- `bazel_api_test.py`: tests
- `ctexplain.py`: stump of an entry point

The tests utilize an existing Python test framework for invoking Bazel (`//src/test/py/bazel:test_base`).

Work towards https://github.com/bazelbuild/bazel/issues/10613

Closes #11511.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel rebuilds only what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
