 #!CommitTicketReference repository="" revision="39563"
 REST API: Allow schema sanitization_callback to be set to null to bypass
 fallback sanitization functions.

 The logic in WP_REST_Request->sanitize_params() added in [39091] did not
 account for `null` or `false` being the sanitization_callback preventing
 overriding `rest_parse_request_arg()`. This fixes that oversight, allowing
 the built in sanitization function to be bypassed. See #38593.

 Props kkoppenhaver, rachelbaker, jnylen0.
 Fixes #39042.
