This is step 1 of ~3, breaking up #14720 into reviewable chunks, with the aim to make syspolicy be a build-time configurable feature. In this first (very noisy) step, all the syspolicy string key constants move to a new constant-only (code-free) package. This will make future steps more reviewable, without this movement noise. There are no code or behavior changes here. The future steps of this series can be seen in #14720: removing global funcs from syspolicy resolution and using an interface that's plumbed around instead. Then adding build tags.
