[aws-ses] Set active receipt rule set

It looks like the [aws-ses module](https://docs.aws.amazon.com/cdk/api/latest/docs/aws-ses-readme.html) does not support [setting an active receipt rule set yet](https://docs.aws.amazon.com/cli/latest/reference/ses/set-active-receipt-rule-set.html). This means we currently have to either go through the console or SDK (or some custom action that I haven't explored yet).

### Use Case

With the CDK I can currently create a receipt rule set, but I cannot activate it (without going through other tools). I would like to create a receipt rule set and directly activate it.

### Proposed Solution

Extend the [ReceiptRuleSet](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ses.ReceiptRuleSet.html) with an option parameter to set it as the defeault.

This is a :rocket: Feature Request

Start with the aws-ses module and its ReceiptRuleSet API, then compare its behavior with the linked AWS CLI set-active-receipt-rule-set operation. Confirm how a receipt rule set is created and how activation should be represented in the CDK API. Done means a ReceiptRuleSet can be created and directly marked as the active set without using the console or SDK.
