feat(autoscaling): add support for InstanceRefresh suspended process (#29113)

Also add InstanceRefresh as a default suspended process for RollingUpdate. 

I have also submitted a request to update https://repost.aws/knowledge-center/auto-scaling-group-rolling-updates to conform with this change. 

### Reason for this change

Instance Refresh is a feature of ASG. It performs a similar function to Rolling Update. If an Instance Refresh is running at the same time as a Rolling Update, the Rolling Update will fail. It is safer to suspend the process. 

### Description of changes

See above.

### Description of how you validated changes

Unit tests.
