Introduce ninja_build for the correct composition of targets.

ninja_graph is responsible now only for parsing the graph and symlinking inputs under output_root. This way it will always be a leaf in the build graph, and all combinations of non-cyclic dependencies between Bazel-built and Ninja-built targets are possible.
ninja_build absorbs parsed NinjaTarget objects through NinjaGraphProvider.
ninja_build creates actions for the subgraph for the targets from output_groups.
Bazel-built dependencies are passed to ninja_build with deps_mapping attribute.
There is an interoperability with Bazel test.

! this CL additionally contains a fix for deps_mapping to also replace the path to bazel-built file in the constructed command line.

Closes #10804.

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.
