Posts, Post Types: Add labels for post transformation messages.

Because the existing `post_updated_messages` filter can be modified dynamically based on post state, it's unreliable to use with REST API clients. Instead, these new labels give clients stateless equivalents.

Props earnjam.
Fixes #45101.
