Sergey Biryukov 68af562077 Code Modernization: Use a consistent check for parent items in WP_Walker.
This affects the `::walk()`, `::paged_walk()`, and `::get_number_of_root_elements()` methods.

PHP 8 changes the way string to number comparisons are performed: https://wiki.php.net/rfc/string_to_number_comparison

In particular, checking if an empty string is equal to zero in PHP 8 evaluates to `false`, not `true`.

For the `WP_Walker` class, this resulted in an incorrect handling of parent items in a few methods.

By explicitly checking for an `empty()` value instead, we make sure the check works as expected in PHP 8 and earlier versions.

Follow-up to [35876], [48960], [49043], [49076].

Props sunxiyuan, aristath, SergeyBiryukov.
