…ory (#2081)

* Register stats directories with Rails::CodeStatistics.register_directory.

Rails `main` uses Thor for the `bin/rails stats` command instead of
Rake. This means stats directories need to be added in the Railtie.

The global constant STATS_DIRECTORIES defined by Rails, has been
deprecated in favor of Rails::CodeStatistics.register_directory.
