Actually remove deprecated jquery_ui libraries from core

Problem/Motivation

In #3051352: [Plan] Remove unused jQuery UI components and replace with a suite of contrib packages for the continuous upgrade path → we deprecated jQuery UI components that core doesn't use.

However, we still need to remove the library definitions from Drupal core.

Some core libraries are still using jquery_ui components directly, like dialog - in these cases, we can't remove the actual files, but we can still remove the library definitions.

We can do this all in one go in this issue I think - should be pure deletion.
