	This cleans up a legacy API from Bazel's "static configuration" days, when transition definitions involved deep and complex logic in the analysis code. That was too much cruft to embed into lib.packages. But the modern definitions are way simpler and thus easier to embed. This change only copies the existing definitions. Because a lot of references will have to be updated, we'll migrate the move over a few changes. PiperOrigin-RevId: 179859293
