(ses): add `configurationSetArn` property on `ConfigurationSet`

### Describe the feature

Add a `configurationSetArn` property exposed on `ConfigurationSet` construct to improve building policies for resource using this ConfigurationSet to send emails with SES.

### Use Case

When granting send email access to a lambda the ARN for the ConfigurationSet must be constructed manually:
```
Grant.addToPrincipal({
grantee,
actions: ["ses:SendEmail"],
resourceArns: [
this.stack.formatArn({
service: 'ses',
resource: 'configuration-set',
resourceName: 'marketing-team-configuration-set',
}),
],
scope: this
})
```

### Proposed Solution

Similar to addition made in https://github.com/aws/aws-cdk/pull/29084 , proposed solution includes building with `formatArn` method the resource underlying ARN.

### Other Information

This paves the way for future `grant` methods on `ConfigurationSet` construct

### Acknowledgements

- [x] I may be able to implement this feature request
- [ ] This feature might incur a breaking change

### CDK version used

2.137.0

### Environment details (OS name and version, etc.)

macOS 14.2.1

Start at the SES ConfigurationSet construct and inspect the analogous change in pull request 29084. Trace how the construct can use formatArn to expose the configuration-set ARN, and consider the work complete when consumers can reference configurationSetArn instead of constructing that ARN manually.
