[11.x] [Meta] Remove deprecated extensions from Drupal 11

I am mistaken and must have read the title wrong and thought it was the deprecation issue. This is the removal issue and it really is a child of 🌱 [meta] Requirements for tagging Drupal 11.0.0-beta1 Active .

Updating title, tags and version number based on recent announcement at https://www.drupal.org/about/core/blog/new-drupal-core-branching-scheme-... →

Fixing attribution.

book is done

Field Layout will move to the deprecation issue made in prep for Drupal 12.

Thank you to everyone who helped complete the deprecation and removal of this 6 extensions from core!
