buffet: Add command_def filtering by command visibility

When updating cloud or local client with the device's CDD make sure
to send only the command definitions that are available to particular
client (local vs cloud).

Also made it possible to subscribe to command definition change notifications
for more than one listener (using base::CallbackList) so that both the local
and cloud adapters can notify the respective clients about command visibility
changes (the actual API to change the command visibility is coming in a
follow-up CL).
