[12.x] [Meta] Remove deprecated extensions from Drupal 12

Problem/Motivation

Remove any extensions deprecated in Drupal 11.

Details on how to remove an extension are in the deprecation policy for modules and themes.

Proposed resolution

Remove modules where agreement was made and modules were deprecated in Drupal 11.

Remaining tasks

This needs to be coordinated with an Issue to add new database dumps, similar to #3414563: Add new 10.3.x database dump fixtures, without modules deprecated for removal in 11.x

Modules

• Ban #3488827: [12.x] [Meta] Tasks to remove Ban module
• Toolbar #3488828: [12.x] [Meta] Tasks to remove Toolbar module
