move pkg/fields to apimachinery
Purely mechanical move of `pkg/fields` to apimachinery.
Discussed with @lavalamp on slack. Moving this an `labels` to apimachinery.
@liggitt any concerns? I think the idea of field selection should become generic and this ends up shared between client and server, so this is a more logical location.

replace global registry in apimachinery with global registry in k8s.io/kubernetes
We'd like to remove all globals, but our immediate problem is that a shared registry between k8s.io/kubernetes and k8s.io/client-go doesn't work. Since client-go makes a copy, we can actually keep a global registry with other globals in pkg/api for now.

Use controller interface for everything in config factory
**What this PR does / why we need it**:
We want to replace controller structs with interfaces
- per the TODO in `ControllerInterface`
- Specifically this will make the decoupling from Config and reuse of the scheduler's subcomponents cleaner.

Predicate cacheing and cleanup
Fix to #31795
First pass @ cleanup and caching of the CheckServiceAffinity function.
The cleanup IMO is necessary because the logic around the pod listing and the use of the "implicit selector" (which is reverse engineered to enable the homogenous pod groups).
Should still pass the E2Es.

Comments addressed, Make emptyMetadataProducer a func to avoid casting,
FakeSvcLister: remove error return for len(svc)=0. New test for
predicatePrecomp to make method semantics explictly enforced when meta
is missing. Precompute wrapper.

[Part 1] Implementation of equivalence pod
Part 1 of #30844
This PR:
- Refactored `predicate.go`, so that `GetResourceRequest` can be used in other places to `GetEquivalencePod`.
- Implement a `equivalence_cache.go` to deal with all information we need to calculate an equivalent pod.
- Define and register a `RegisterGetEquivalencePodFunction `.
Work in next PR:
- The update of `equivalence_cache.go`
- Unit test
- Integration/e2e test
I think we can begin from the `equivalence_cache.go`? Thanks. cc @wojtek-t @davidopp
If I missed any other necessary part, please point it out.
