[Feature]: Transform client created from constructors derived from destructuring assignment

### Self-service

- [ ] I'd be willing to implement this feature

### Problem

```js
import AWS from "aws-sdk";
const { DynamoDB } = AWS;
const client = new DynamoDB();
```

### Solution

```js
import { DynamoDB } from "@aws-sdk/client-dynamodb";
const client = new DynamoDB();
```

### Alternatives

N/A

### Additional context

Noted when working on utility https://github.com/aws/aws-sdk-js-codemod/pull/781

The issue names no files or tests; begin by reviewing the utility referenced by pull request #781 and tracing the existing AWS SDK constructor transforms. Use the destructuring example as the starting case, and consider the work done when that pattern produces the shown modular import and constructor transformation.
