feat(iot): device certificate age check audit configuration (#33816)

### Issue # (if applicable)

None

### Reason for this change

AWS IoT now supports for new audit configuration about device certificate age check.
https://docs.aws.amazon.com/iot-device-defender/latest/devguide/device-certificate-age-check.html

### Description of changes

- Add `deviceCertificateAgeCheck` to `CheckConfiguration`
  - To enable audit configuraiton
- Add `deviceCertificateAgeCheckDuration` to `CheckConfiguration`
  - To configure threshold duration in days

### Describe any new or updated permissions being added

None

### Description of how you validated changes

Add both unit and integ tests

+To configure [the device certificate age check](https://docs.aws.amazon.com/iot-device-defender/latest/devguide/device-certificate-age-check.html), you can specify the duration for the check:
+
+```ts
+import { Duration } from 'aws-cdk-lib';
+
+new iot.AccountAuditConfiguration(this, 'AuditConfiguration', {
+  checkConfiguration: {
+    deviceCertificateAgeCheck: true,
+    // The default value is 365 days
+    // Valid values range from 30 days (minimum) to 3652 days (10 years, maximum)
+    deviceCertificateAgeCheckDuration: Duration.days(365),
+  },
+});
+```
+
 ### Scheduled Audit
 
 You can create a [scheduled audit](https://docs.aws.amazon.com/iot-device-defender/latest/devguide/AuditCommands.html#device-defender-AuditCommandsManageSchedules) that is run at a specified time interval. Checks must be enabled for your account by creating `AccountAuditConfiguration`.
