Promotes Source IP preservation for Virtual IPs from Beta to GA

Fixes #33625. Feature issue: kubernetes/features#27.

Bullet points:
- Declare 2 fields (ExternalTraffic and HealthCheckNodePort) that mirror the ESIPP annotations.
- ESIPP alpha annotations will be ignored.
- Existing ESIPP beta annotations will still be fully supported.
- Allow promoting beta annotations to first class fields or reversely.
- Disallow setting invalid ExternalTraffic and HealthCheckNodePort on services. Default ExternalTraffic field for nodePort or loadBalancer type service to "Global" if not set.

**Release note**:

```release-note
Promotes Source IP preservation for Virtual IPs to GA.

Two api fields are defined correspondingly:
- Service.Spec.ExternalTrafficPolicy <- 'service.beta.kubernetes.io/external-traffic' annotation.
- Service.Spec.HealthCheckNodePort <- 'service.beta.kubernetes.io/healthcheck-nodeport' annotation.
```
