GCE: Fix ILB issue updating backend services
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#62878
`ensureInternalBackendServiceGroups` would sync the instance groups with the latest nodes, and update the backend service's list of backends if necessary. However, the list of backends on the backend service was not set before calling the GCP API.
`updateInternalLoadBalancerNodes` does very little above `ensureInternalBackendServiceGroups`, so I'm just combining the unit tests into one.
