Store SkyValues for new deps from the graph intra-environment This ensures that if a SkyFunction read a value (or its absence) for a dep during its evaluation, subsequent requests for that dep's value (or its absence) provide the same result. This does not yet necessarily apply to the process of collecting events and posts from a node's deps, which will be considered in a future refactoring. This CL adds SkyFunctionEnvironment#removeUndoneNewlyRequestedDeps because the prior strategy for removing undone deps for done parents, by re-requesting the dep's node from the graph and checking its doneness, could lead to deps being dropped from parents if those deps transitioned from done to dirty as the parent completes. Minor cleanup to the bubbleErrorInfo field, which is nullable, and now documented. (Note that done->dirty node transitions during evaluation are planned, but not yet possible.) RELNOTES: None.

{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.
