Only allow regular files and directories spawn outputs to be uploaded to a remote cache. The remote cache protocol only knows about regular files and directories. Currently, during action output upload, symlinks are resolved into regular files. This means cached "executions" of an action may have different output file types than the original execution, which can be a footgun. This CL bans symlinks from cachable spawn outputs and fixes https://github.com/bazelbuild/bazel/issues/4840. The interface of SpawnCache.CacheHandle.store is refactored: 1. The outputs parameter is removed, since that can be retrieved from the underlying Spawn. 2. It can now throw ExecException in order to fail actions. Closes #4902.

{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.
