feat(lambda): support observability for ESM ( DDB, Kinesis, SQS) (#32204)

### Reason for this change

Lambda is introducing a new property in Event Sources named `MetricsConfig` to get enhanced metrics for user's event source that captures each stage of processing. Through this metrics customer can track flow of events through their EDA pipelines. 

This feature is currently supported for `DynamoDB`, `Kinesis` and `SQS` event sources only.
### Description of changes

This new property can be opted in by setting the `MetricsConfig` field while creating event sources. The example of opting for `MetricsConfig` for dynamoDB event is shown below:

```
fn.addEventSource(new eventsources.DynamoEventSource(table, {
  startingPosition: lambda.StartingPosition.LATEST,
  metricsConfig: {
    metrics: [MetricType.EVENT_COUNT],
  }
}))
```

Today there is only 1 metric type: EventCount. The `metrics` array can be either one element with `EventCount` or an empty array. More configuration support will be available in future

### Description of how you validated changes

Have added unit test and integration test to validate the implementation
