This is phase 2 of of the switch to toolchain transitions. See bazelbuild/bazel#11584 for details. This shouldn't be merged into rules_swift's master branch until https://cs.opensource.google/bazel/bazel/+/58fdf63d81cc71f0315918b111fc56f4c039f1a5 is in a Bazel release (which should be 3.7, bazelbuild/bazel#12188).
