fix(elbv2): BaseLoadBalancer.vpc is not optional

The `BaseLoadBalancer.vpc` property fulfills the `IApplicationLoadBalancer.vpc` and `INetworkLoadBalancer.vpc` properties, both of which are optional. A bug in `jsii` (see aws/jsii#3342) makes this pass type system consistency checks, when it should not be allowed.
