…s to binaries built with `swift_{binary, compiler_plugin, test}`.
This is necessary to ensure that these binaries run correctly when using APIs like `Span` that are back-deployed on older OSes. Since the `swift_*` rules don't do bundling of their own, we simply point to the libraries in the toolchain itself (using the `xcode-select`-dependent symlinks, as we were already doing for tests). To actually distribute such a binary, it's the responsibility of the user to include the required dylibs with it (or, better, use a rule from rules_apple to perform the bundling).
I've explicitly ignored the swift-5.0 and swift-5.5 directory since we have no plans to deploy anything from these rules to such old OSes.
