Handle exceptions encountered resolving packages during the execution phase

Currently we may do lookups of not-already-cached packages during the
execution phase for actions that discover inputs. Exceptions encountered
during this would go unhandled and result in a crash. Here we introduce
PackageRootResolutionException which wraps these exceptions and triggers
an ActionExecutionException which is cleanly handled in the exec phase.

As part of this change SkyframeActionExecutor#getArtifactRoots(...) will
fail properly on errors getting package roots.

Bazel (Alpha)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
