General: Handle missing field in WP_List_Util::pluck(). 

Handles when the `$field` (i.e. key or property) is missing in one of the `$input_list` items by checking the key (array) or property (object) exists before using it for assignment.

Resolves the following bugs:

* a PHP warning for undefined key|property.
* `null` being set for that array or object within the returned list.

The changes resolve the issues in both `WP_List_Util::pluck()` (if invoked directly) and `wp_list_pluck()`.

Also includes an additional test for the scenario where the `wp_list_pluck()` `$index_key` is not `null`, the `$field` is missing in one of the `$input_list` items.

Follow-up to [55423], [51663], [42527], [38928].
