Fixes#4987
As machinery is supposed to be widely used project, and gRPC lacks
proper support to override default codec easily, it might come into
conflict with other projects.
Instead, move codec to core talos, and register it explicitly in the
server code (which covers machined, apid, trustd) and client code
(talosctl).
