Fix StatefulSet set-based selector bug

**What this PR does / why we need it**:
ControllerRevisions were using selectors as the labels, in case of set-based selectors, the helper function to convert selectors to labels would break. This PR uses pod labels for ControllerRevision labels instead of selectors.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #59266

**Special notes for your reviewer**:
I'm trying to learn Kubernetes codebase and would be happy to make changes if anything is off.
**Release note**:

```release-note
Fix StatefulSet to work with set-based selectors.
```
