Use k8s.io/utils/ptr in pkg/proxy (#121154)

* Use k8s.io/utils/ptr in pkg/proxy

* Replace pointer.String(), pointer.StringPtr(), and pointer.Bool() with ptr.To()

* Replace pointer.Int32(constexpr) with ptr.To[int32](constexpr)

* Replace pointer.Int32(int32(var)) with ptr.To(int32(var))

* Replace remaining pointer.Int32() cases with ptr.To

* Replace 'tcpProtocol := v1.ProtocolTCP; ... &tcpProtocol', etc with ptr.To(v1.ProtocolTCP)

* Replace 'nodeName = testHostname; ... &nodeName' with ptr.To(testHostname)

* Use ptr.To for SessionAffinityConfig.ClientIP.TimeoutSeconds

* Use ptr.To for InternalTrafficPolicy

* Use ptr.To for LoadBalancer.Ingress.IPMode
