class BcRoute in Drupal 9

A backwards compatibility route.

When a route is deprecated for another one, and backwards compatibility is provided, then it's best practice to:

• not duplicate all route definition metadata, to instead have an "as empty as possible" route
• have an accompanying outbound route processor, that overwrites this empty route definition with the redirected route's definition.
