Add DNS config for API, API-Int and Ingress to AWSPlatformStatus

Add DNS record types and LB IP adresses for API, API-Int and Ingress
to the AWSPlatformStatus when the userConfiguredDNS feature is
enabled. These values would be used to configure the in-cluster DNS
and after cluster install would be available to the user to configure
their custom DNS solution.
