Add missing doc blocks to revision.php.

Clarify `@return` values where necessary.
In `wp_delete_post_revision()`, `wp_delete_post()` doesn't return `WP_Error`, so that check can be removed.
`wp_revisions_to_keep()` always returns an `int`, so `wp_revisions_enabled()` can use strict comparison.
 
See #32444.
