feat(ecs): support for explicit activation of the circuit breaker (#28611)

This PR has enabled explicit disabling of the circuit breaker. 

```ts
declare const cluster: ecs.Cluster;
declare const taskDefinition: ecs.TaskDefinition;
const service = new ecs.FargateService(this, 'Service', {
  cluster,
  taskDefinition,
  circuitBreaker: {
    enable: true, // added
    rollback: true
  },
});
```

This is useful for removing a circuit breaker that has been set previously.

Closes #27131.
