Windows, JNI: rewrite CreateJunction

In this PR:

- replace custom JunctionDescription definition
  with REPARSE_DATA_BUFFER from MSDN

- clean up kMaxJunctionTargetLen computation

- use already-computed offsets when creating the
  PathBuffer

Motivation:

- I'm implementing readSymbolicLink. It should
  handle junctions as well as symlinks. (There can
  be pre-existing symlink created from Admin
  shells, or the user may have enabled
  unprivileged symlink creation.)

- REPARSE_DATA_BUFFER contains structs in a union
  for junction and symlink data, and is the
  idiomatic struct definition to work with
  FSCTL_SET_REPARSE_POINT/FSCTL_GET_REPARSE_POINT.

See https://github.com/bazelbuild/bazel/issues/7907

Closes #7928.

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.
