Remove the dependency on Classy as a base theme

Problem/Motivation

Classy will be deprecated in Drupal 9 and moved to contrib prior to the Drupal 10.0.0 release. Source: https://www.drupal.org/node/3103178 →
Core themes no longer have their base themes set to Classy and have copied over Classy templates & CSS. ( https://www.drupal.org/project/drupal/issues/3050389 → )

Proposed resolution

Set the theme's base theme to 'false'.

User interface changes

Removing Classy without copying over its templates and CSS will most likely not affect the base theme. (This is currently being tested here with the unchanged child theme that ships with this theme: https://test-uswds.pantheonsite.io/ ) However it is very likely to cause breaking changes to child themes that might have inherited Classy's templates and CSS.

    As an FYI I just wanted to post this here for informational purposes but for some this dependency is a Drupal 10 upgrade blocker. I have found that the easiest way to move into Drupal 10 before this dependency change is made from this ticket's work is to install 'Classy' AND 'Stable' (Classy's base theme is Stable) as contributed themes. This will allow the current version of the USWDS's theme to be installed in Drupal 10.

    Even though these themes have been removed from core they can still be side loaded leading to a successful Drupal 10 upgrade even with USWDS dependency requirements.
