[google-cloud-cpp] use features to stop package growth (#19600)

* [google-cloud-cpp] use features to stop package growth

We have plans to grow `google-cloud-cpp`, but we think the build times
are large enough already. This creates "features" to at least stop the
package growth as new features are added. The "default-features"
reflects the current features in the package.

* Remove versions created during development

* Address review comments
