(core): PhysicalNames and Nested Stacks

### Describe the bug

When the physicalName is generated (`Resource` `generatePhysicalName()`) for a resource inside a `cdk.NestedStack`, the name generated is incorrect as it contains the stack "Token identifier" instead of the substituted value.

### Expected Behavior

The pyshicalName is generated correctly

### Current Behavior

The physical name looks something like this: `"${token[token.399]}estacknestedtest2ad16ad137c06fec44b9"`.

### Reproduction Steps

Create something like the following

```
const app = new cdk.App();
const stack1 = new ServiceStack(app, "ServiceStack", {
env: {
account: '111111',
region: 'us-east-1'
}
});

new ServiceStack(app, "ServiceStack2", {
env: {
account: '111111',
region: 'eu-west-1'
}
refBucket: stack1.nestedBucket,
});

export type ServiceStackProps = cdk.StackProps & {
refBucket?: s3.IBucket;
};

export class ServiceStack extends cdk.Stack {
public nestedBucket: s3.IBucket;

constructor(scope: Construct, id: string, props: ServiceStackProps) {
super(scope, id, props);

const nested = new ServiceNested(this, "Nested", {});
this.nestedBucket = nested.nestedBucket;

props.refBucket &&
new cdk.CfnOutput(this, "OutRef", {
value: props.refBucket.bucketName,
});
}
}

export class ServiceNested extends cdk.NestedStack {
public nestedBucket: s3.IBucket;

constructor(scope: Construct, id: string, props: cdk.NestedStackProps) {
super(scope, id, props);

this.nestedBucket = new s3.Bucket(this, "Test", {
bucketName: cdk.PhysicalName.GENERATE_IF_NEEDED,
});
}
}

```

You will see in the synth output:

```
"Outputs": {
"OutRef": {
"Value": "${token[token.399]}estacknestedtest2ad16ad137c06fec44b9"
}
},
```
