ci-automation/vendor-testing/gce.sh: Test GVNIC and break retest cycle

The logic we had in some tests for covering different instance types
now got more easy to reuse for testing the GVNIC mode in GCE.
Align the GCE test with AWS and DigitalOcean to test an additional
"instance type" (here just changing the NIC) and break the retest spin
case it gets called for arm64.
