Placeholder for enforcement of the legacy core/platform API restriction.

This does is as similar as possible to the equivalent changes in AOSP
and internal masters, without actually doing any enforcement. This
means we don't have to maintain a third hard-coded list for rvc, while
minimizing the diffs. The list here is identical to the one in AOSP
master, so changes from there should merge down cleanly (and have no
effect).
