Move kubeproxy ComponentConfig external types to `k8s.io/kube-proxy`

**What this PR does / why we need it**:
This PR implements most of kubernetes/community#2354 for the kube-proxy.
The PR:
- Moves k8s.io/kubernetes/pkg/proxy/apis/kubeproxyconfig as-is to k8s.io/kubernetes/pkg/proxy/apis/config as agreed
- Moves the external types to the new staging repo k8s.io/kube-proxy, in the k8s.io/kube-proxy/config/v1beta1 package.
- Makes k8s.io/kubernetes/pkg/proxy/apis/config/v1beta1 source the types from k8s.io/kube-proxy/config/v1beta1. The defaulting and conversion code is kept in this package as before.
- All references to these packages have been updated.

Ref #67233

**Special notes for your reviewer**:
