Tag Security Group created for AWS ELB with same additional tags as ELB

/sig aws

(I worked on this with @bkochendorfer)

Tags the SG created for the ELB with the same additional tags the ELB gets from the `service.beta.kubernetes.io/aws-load-balancer-additional-resource-tags` annotation. This is useful for identifying orphaned resources.

We think that reusing the annotation is a simpler and less intrusive approach than adding a new annotation, and most users will want the same set of tags applied.

We weren't sure how to write a test for this because it looks like the fake EC2 code doesn't store the state of the security groups. If new tests are a requirement for merging, we'll need help writing them.

Fixes #53489

```release-note
AWS Security Groups created for ELBs will now be tagged with the same additional tags as the ELB (i.e. the tags specified by the "service.beta.kubernetes.io/aws-load-balancer-additional-resource-tags" annotation.)
