fix(cloudformation-include): parse MinActiveInstancesPercent in AutoScalingRollingUpdate policy (#33852)

### Issue #33810 

Closes #33810.

### Reason for this change

When using CfnInclude to import existing CloudFormation templates, the MinActiveInstancesPercent property in AutoScaling 
group update policies was being silently dropped because it was missing from both the `CfnAutoScalingRollingUpdate` 
interface in `cfn-resource-policy.ts` and the parser in the `parseAutoScalingRollingUpdate` function in `cfn-parse.ts`.

### Description of changes

This fix adds:
1. The missing `minActiveInstancesPercent` property to the `CfnAutoScalingRollingUpdate` interface in `cfn-resource-policy.ts`
2. The corresponding property parser to the `parseAutoScalingRollingUpdate` function in `cfn-parse.ts`

These changes ensure that the `MinActiveInstancesPercent` property is correctly preserved when importing templates with 
`AutoScalingRollingUpdate` policies.


### Describe any new or updated permissions being added

N/A

### Description of how you validated changes

Added a comprehensive test that verifies all properties of `AutoScalingRollingUpdate` are correctly parsed, including a new
test template with all properties and explicit assertions for each property.
