chore(ec2): add VPC interface endpoints for WAFV2 (#33685)

### Issue # (if applicable)

### Reason for this change

There are no VPC endpoints for AWS WAFV2 so I added.
```
% aws ec2 describe-vpc-endpoint-services --filters "Name=service-name,Values=*waf*" --region us-east-1 --query "ServiceNames[]" 
[
    "com.amazonaws.us-east-1.wafv2",
    "com.amazonaws.us-east-1.wafv2-fips"
]
```
