feat: add refs support for various fields

The following fields have had refs support added:

- CacheSubnetGroup.SubnetIDs: ec2.Subnet.Status.SubnetID
- ReplicationGroup.CacheParameterGroupName: CacheParameterGroup.Spec.CacheParameterGroupName
- ReplicationGroup.CacheSubnetGroupName: CacheSubnetGroup.Spec.CacheSubnetGroupName
- ReplicationGroup.SecurityGroupIDs: ec2.SecurityGroup.Status.ID

Closes aws-controllers-k8s/community#1513
Closes aws-controllers-k8s/community#1860
