The internal GCP package used `pkg.go.dev/google.golang.org/api` [1] to
interact with Compute Engine API. Modify the package to use the new and
idiomatic `pkg.go.dev/cloud.google.com/go` [2] library for interacting
with the Compute Engine API. The new library have been already used to
interact with the Cloudbuild and Storage APIs. The new library was not
used for Compute Engine since the beginning, because at that time, it
didn't support Compute Engine.
Update go.mod and vendored packages.
