Read all resources for finalization and gc, not just preferred

Fixes #31481. 

Currently when starting namespace controller or garbage collector we only gather preferred version resources, which in case of multiple versions (you guessed it `batch/v2alpha1.CronJobs` again) isn't sufficient. This PR adds additional method which actually retrieves all resources from all versions and works on them.
