Unbundle Android tools from Bazel's binary

Create a new package containing an external repository that the Android rules depend on at runtime.

This is an interim solution to extract dependencies out from the Bazel binary to minimize its size. The final goal is to extract all Android rules and tools out of Bazel and into rules_android and tools_android.

This change contains a new script, upload_android_tools.sh, for creating a tarball containing two runtime dependencies of the Android rules: all_android_tools_deploy.sh and ImportDepsChecker_deploy.jar. The script then versions the tarball and uploads it to GCS.

This also adds the http_archive call to the Android tools' implicit WORKSPACE to fetch the external repository. Due to this new external repository dependency, we have to add it to the distribution archive for testing as well, and renamed it from jdk_WORKSPACE to test_WORKSPACE to more accurately capture its purpose.

This is not an incompatible change and will be transparent to end users.

New Bazel size after this change, compiled with -c opt:

$ ls -lah bazel-bin/src/bazel

Fixes #1055

RELNOTES: Bazel is now ~20MiB smaller, from unbundling the Android rules' runtime dependencies.

Closes #7900.

Bazel

{Fast, Correct} - Choose two

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

  • Speed up your builds and tests: Bazel only rebuilds 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.
