Subject: [PATCH] Tests: Fix unit test failure in PHP 8.5 due using null as an
 array offset.

This adds `is_string()` type checks for the `$post_status` arg passed to both `get_post_status_object()` and `is_post_status_viewable()`. This was triggered by `Tests_Post_IsPostStatusViewable::test_built_in_and_unregistered_status_types()` for the `null` data set.

Follow-up to [61170].

See #63167, #63061.
