Message:

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.
