Implement `DrupalRectorSettings`
### Problem/Motivation Introduces a settings service for global drupal-rector configuration with constructor injection, replacing the static version-override hack. Allows controlling backward-compatibility wrapping and minimum core version support, wired automatically in rector.php. ### Work items - Commit(s): [9c1e03a386](https://github.com/palantirnet/drupal-rector/commit/9c1e03a38651), [14dd167aef](https://github.com/palantirnet/drupal-rector/commit/14dd167aefcf), [15bf5d18ae](https://github.com/palantirnet/drupal-rector/commit/15bf5d18ae04), [421bf32e05](https://github.com/palantirnet/drupal-rector/commit/421bf32e050b) ### Credit - Implemented by: @bbrala --- *Filed retroactively as part of the Drupal 12 rector coverage effort.
