Coding Standards: Explicitly return `null` in `_wp_filter_build_unique_id()`.
This commit updates the function to explicitly return `null` if a valid `$callback` is not passed. Previously, the function could return `void`, but was typed as only returning a string.
Follow-up to [5936], [11409], [12090], [46220], [46801], [50807], [52300].
Props justlevine.
See #63268.
