fix(dotnet): add missing GetInterfaceType in the .NET runtime (#703)

Add support for return type being array of interfaces. Tested with the customer code. https://docs.aws.amazon.com/cdk/api/latest/dotnet/api/Amazon.CDK.AWS.EC2.Vpc.html#Amazon_CDK_AWS_EC2_Vpc_PrivateSubnets This was not supported by the runtime, as it only allowed for classes and enums: ``` public virtual IISubnet[] PrivateSubnets { get; } ``` Fixes aws/aws-cdk#2362
