Change equivalence class hashing function
**What this PR does / why we need it**:
This updates the Pod equivalence class hashing function to hash pod fields which are read by scheduler predicates. Until now, we used a pod's OwnerReference as a shorthand for equivalence, but not all controllers will create homogeneous sets of pods.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
/ref #58222
**Performance impact**:
Hashing is not expensive enough to impact scheduling performance.
