* Removes metadata matching criteria from a site.

* You can match based on the key, or key and value. Removing based on key and
* value, will keep from removing duplicate metadata with the same key. It also
* allows removing all metadata matching key, if needed.
*
* @since 5.1.0
*
* @param int $site_id Site ID.
* @param string $meta_key Metadata name.
* @param mixed $meta_value Optional. Metadata value. If provided,
* rows will only be removed that match the value.
* Must be serializable if non-scalar. Default empty.
* @return bool True on success, false on failure.
