(aws-ecs-patterns): support AvailabilityZoneRebalancing

### Describe the feature

The current ecs patterns, such as `ApplicationLoadBalancedFargateService`, have their rebalancing set to the default, which is disabled. It cannot be updated on the `FargateService` itself.

### Use Case

AWS just spread an email around, saying that new ECS services will automatically have this set to enabled. It'd be good that we can also enable this for existing services, or explicitly disable for new ones if that's not desired.

### Proposed Solution

### Acknowledgements

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

### AWS CDK Library version (aws-cdk-lib)

2.187.0

### AWS CDK CLI version

2.1003.0

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

MacOS 14

Start by reading the AWS CDK ECS patterns around ApplicationLoadBalancedFargateService and FargateService, focusing on how service options are exposed and passed through. Check the related tests for these patterns. Done means existing services can enable AvailabilityZoneRebalancing and new services can explicitly enable or disable it.
