Remove "Always show advanced display settings" setting

Thanks for starting on this. As well as removing the checkbox we need to remove the related code in the submit handler, any code that refers to the ui.show.advanced_column setting, and also remove it from existing site config in a post-update hook. 📌 Get rid of using 'views.settings':skip_cache in ViewsData Fixed might be useful for reference where we removed another setting like this.

Added patch please review.

Don't see removal of the site config or post_update hook.

Removed the

ui.show.advanced_column

settings from the code mentioned in comment#3
