Implement equivalence cache by caching and re-using predicate result

The last part of #30844, I opened a new PR instead of overwrite the old one because we changed some basic assumption by allowing invalidating equivalence cache item by individual predicate.

The idea of this PR is based on discussion in https://github.com/kubernetes/kubernetes/issues/32024

- [x]  Pods belong to same controllerRef considered to be equivalent
- [x] ` podFitsOnNode` will use cached predicate result if it's available
- [x] Equivalence cache will be updated when if a fresh new predicate is done
- [x] `factory.go` will invalid specific predicate cache(s) based on the object change
- [x] Since `schedule` and `bind` are async, we need to optimistically invalid affected cache(s) before `bind`
- [x] Fully unit test of affected files
- [x] e2e test to verify cache update/invalid workflow
- [x] performance test results

- [x] Some nits fixes related but expected to result in `needs-rebase` so they are split to: #36060 #35968 #37512

**Special notes for your reviewer**:
- I remove the commented test cases and just leave TODOs instead. I think converting these untestable test cases for now is not necessary. We can add new test cases in future.
- I remove the e2e test case `validates that embedding the JSON PodAffinity and PodAntiAffinity setting as a string in the annotation value work` because we have a test case `validates that InterPod Affinity and AntiAffinity is respected if matching` to test the same thing.

Static deepcopy – phase 1

This PR is the follow-up of https://github.com/kubernetes/kubernetes/pull/36412, replacing the
dynamic reflection based deepcopy with static DeepCopy+DeepCopyInto methods on API types.

This PR **does not yet** include the code dropping the cloner from the scheme and all the
porting of the calls to scheme.Copy. This will be part of a follow-up "Phase 2" PR.

A couple of the commits will go in first:
- [x] audit: fix deepcopy registration  https://github.com/kubernetes/kubernetes/pull/48599
- [x] apimachinery+apiserver: separate test types in their own packages #48601 
- [x] client-go: remove TPR example #48604
- [x] apimachinery: remove unneeded GetObjectKind() impls #48608 
- [x] sanity check against origin, that OpenShift's types are fine for static deepcopy https://github.com/deads2k/origin/pull/34

TODO **after** review here:
- [x] merge https://github.com/kubernetes/gengo/pull/32 and update vendoring commit
