fix(rds): can not lookup VPC Security Groups with fromLookup method (#34906)

### Issue # (if applicable)
N/A

### Reason for this change
Currently, the fromLookup method uses `DBSecurityGroups`, which is designed for EC2-Classic resources. 
However, since EC2-Classic was retired, this property is no longer relevant.

Reference: 
* https://repost.aws/questions/QUK2WnHCaYQxqkXbDBS5fODA/is-it-still-ok-to-use-aws-rds-dbsecuritygroup-in-cloudformation-templates
* https://docs.aws.amazon.com/ja_jp/AWSCloudFormation/latest/TemplateReference/aws-resource-rds-dbsecuritygroupingress.html



### Description of changes
Added `VPCSecurityGroups` to the `fromLookup` method to properly handle VPC security group lookups.



### Describe any new or updated permissions being added
N/A



### Description of how you validated changes
Add unit tests and an integ test.
