Introduce `ActionDispatch::Routing::ConsoleFormatter::Base`

- Create `Base` and inherit `Sheet` and `Expanded` in order to
- prevent code duplication.
  - Remove trailing "\n" for components of `Expanded`.
  - There is no need for `Expanded#header` to return `@buffer` so return `nil` instead.

- Change `no_routes` message "No routes were found for this controller"
  since if use `-g`, it sounds incorrect.
  - Display `No routes were found for this controller.` if apply `-c`.
  - Display `No routes were found for this grep pattern.` if apply `-g`.
