Add a defaults target that all targets linking to aconfig codegen with
the new storage API dependencies will need. The target takes the new
storage APIs conditionally behind a flag, so we can disable it easily.
In this topic, we add it to a single target to see that it builds and
adds the dependency. In follow-on CLs we can add it to the rest of the
targets.
