naming: make the reference lookups a rebuild uses public

The corpus naming test (next commit) records what every stored face and
edge name resolves to, and must find it exactly as a rebuild does. Three
lookups were crate-private: `locate_face_on_body` (a feature's face
points, tried on the body the feature names first), `blend_target` (the
body a fillet or chamfer rounds) and `Document::anchored_face_indices`
(the faces a face-attached sketch is on). Visibility only; no behaviour
changes.
