General: Introduce a wp_list_sort() helper function, v2.

In addition to `wp_list_filter()` for filtering a list of objects, and `wp_list_pluck()` for plucking a certain field out of each object in a list, this new function can be used for sorting a list of objects by specific fields. These functions are now all contained within the new `WP_List_Util()` class and `wp_list_sort()` is used in various parts of core for sorting lists.

This was previously committed in [38859] but got reverted in [38862] and [38863]. To fix the previous issues, `wp_list_sort()` supports now an additional argument to preserve array keys via `uasort()`.

Fixes #37128.
