Remove the ability to view the post listing screen and post editing screen for post types with show_ui set to false. It is unexpected and unintended behaviour that this is allowed.

If your plugin or site does rely on this behaviour, the arguments that are passed to `register_post_type()` should be altered so that `show_ui` is `true`, and arguments such as `show_in_menu`, `show_in_nav_menus`, and `show_in_admin_bar` are `false`.

Fixes #33763
