REST API: Generate sample permalink only when a dependent field is requested.

The sample permalink will now only be generated if the derivative `permalink_template` or `generated_slug` fields are to be included in the response, preventing an unnecessary database request for each post (via `wp_unique_post_slug()`) when those fields are not requested.

Props dlh.
See #45605.
