feat(ngcc): migrate services that are missing `@Injectable()` (#33362)
A class that is provided as Angular service is required to have an `@Injectable()` decorator so that the compiler generates its injectable definition for the runtime. Applications are automatically migrated using the "missing-injectable" schematic, however libraries built for older version of Angular may not yet satisfy this requirement. This commit ports the "missing-injectable" schematic to a migration that is ran when ngcc is processing a library. This ensures that any service that is provided from an NgModule or Directive/Component will have an `@Injectable()` decorator. PR Close #33362
