Make runfiles usage on Windows more flexible to support remote execution.

When trying to find a runfile on Windows:

1. First look for the runfiles MANIFEST and find runfile locations using this if it exists (current behavior).

2. If no MANIFEST file exists, look for runfiles in the runfiles directory (new behavior).

As part of this, remove setting RUNFILES_MANIFEST_ONLY for the benefit of test-setup.sh. Instead of telling it what to do, it decides what to do based on the observed state of the world. Launchers still set RUNFILES_MANIFEST_ONLY for the benefit of launched programs, since some may depend on this.

Fixes https://github.com/bazelbuild/bazel/issues/4962.

RELNOTES: Remote execution works for Windows binaries with launchers.

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.
