Subject: [PATCH] Coding Standards: Rename the `$user_id` parameter of
 `get_user_locale()` to `$user` for accuracy.

Since the parameter accepts not only a user's ID, but also a `WP_User` object, `$user` is a more appropriate name, which better aligns with the `$post` parameter of functions that accept a post ID or a `WP_Post` object.

The pre-existing internal `$user` variable which contained a `WP_User` object is renamed to `$user_object` for clarity.

Follow-up to [38955].

Props aristath, poena, afercia, SergeyBiryukov.
See #55647.
