Move deleteTree and deleteTreesBelow into FileSystem and Path.

The current implementation of these functions is very inefficient and
degrades overall performance significantly, especially when sandboxing is
enabled. However, that's almost the best we can do with a generic
algorithm.

To make room for optimizations that rely on specific file system features,
move these functions into the FileSystem class. I will supply a custom
implementation for UnixFileSystem later.

Note that this is intended to be a pure code move. I haven't applied any
improvements to the code nor tests yet (with the exception of cleaning up
docstrings).

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.
