Subject: [PATCH] General: Revert strict comparison in `WP_List_Util` for now.

Casting the values to a string causes `Array to string conversion` PHP warnings, so using loose comparison restores the previous behavior for code relying on type juggling when using the `wp_list_filter()` function, e.g. comparing a numeric string to an integer.

The unit test case added for this scenario in the previous commit remains.

Follow-up to [55908], [56137].

See #57839.
