Track detailed failures in ErrorSensingEventHandler, use in query

This adds functionality to ErrorSensingEventHandler to support
remembering properties of error events, alongside whether any event was
an error at all.

Note that the new functionality does not explicitly specify
DetailedExitCode, FailureDetails, or types like those, which do not
belong in the general lib/events package.

This uses the new functionality in parts of Bazel's query evaluation
infrastructure to relay details about failure modes which don't result in
the evaluation's immediate termination (via, e.g., exception; this is
common when in "keep going" mode).

Subsequent CLs extend this work to more aspects of query evaluation. This
establishes a foundation for that work.

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.
