message: build: add support for running builds outside of sandbox on Mac.
  Add following to your `~/.bazelrc`. This will run the build faster locally
  (outside of sandbox), but continue running the builds with sandboxing
  on CI.
  ```
  build --spawn_strategy=standalone --strategy=ESM5=sandboxed
  ```
