Swift-autolink-extract and swift-indent missing from recent toolchains

Was this intentional? On further investigation, it seems like everything marked as an editor-integration tool in CMake is no longer included in OSS toolchains or Xcode, at least on macOS. swift-autolink-extract isn't an editor integration tool, but seems to have gone missing between Swift 5.1 and 5.2. swift-indent and others look like they may have been removed between 5 and 5.1.

I think this may have to do with discrepancies between mixin_buildbot_install_components and mixin_buildbot_install_components_with_clang in the build preset definitions, but didn't want to file a bug if it was decided not to ship these tools anymore.
