Convert directDeps to a map of SkyValues

SkyFunctionEnvironment only cares about directDeps' values, not other
NodeEntry data.

This reduces the space of code which could be sensitive to nodes which
transition from done to dirty during evaluation.

To prevent check-then-act races in the refactored code (and only there;
other code will be fixed in future refactorings), instead of checking
deps' isDone() methods before accessing their value, allow
getValueMaybeWithMetadata to be called when not done, and have it return
null when not done.

(Note that done->dirty node transitions during evaluation are planned,
but not yet possible.)

RELNOTES: None.

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.
