fix(eks): changing the subnets or securityGroupIds order causes an error (#24163)

When the subnet list is passed to the EKS Cluster construct in a different order, an update is triggered to the EKS cluster. 
The update process fails as it falsely identifies a change for an unsupported update, although the list has the same items.

The solution is to change the analyzeUpdate function to return `updateVpc: false` if only the securityGroups/subnetsId order has been changed.
