What this PR does / why we need it:

  • Promotes the AdmissionReview API types to v1 with no schema changes
  • Updates the webhook dispatcher to be able to send/receive v1 AdmissionReview objects
  • Tightens response validation for v1 AdmissionReview objects to verify apiVersion/kind/response.patchType/response.uid
  • Adds integration tests to exercise registering for v1 webhooks receiving/returning v1 AdmissionReview objects

Which issue(s) this PR fixes:
Fixes #79893

Does this PR introduce a user-facing change?:

The `AdmissionReview` API sent to and received from admission webhooks has been promoted to `admission.k8s.io/v1`. Webhooks can specify a preference for receiving `v1` AdmissionReview objects with `admissionReviewVersions: ["v1","v1beta1"]`, and must respond with an API object in the same `apiVersion` they are sent. When webhooks use `admission.k8s.io/v1`, the following additional validation is performed on their responses:
* `response.patch` and `response.patchType` are not permitted from validating admission webhooks
* `apiVersion: "admission.k8s.io/v1"` is required
* `kind: "AdmissionReview"` is required
* `response.uid: "<value of request.uid>"` is required
* `response.patchType: "JSONPatch"` is required (if `response.patch` is set)
