[roll] Roll fuchsia [driver][compat] add device_server async init

Adds async initialization logic to the compat::DeviceServer that
automatically sets up the device server based on the incoming directory
and serves it to the outgoing. This also allows the user to easily
forward metadata and avoid manually getting the topological path.
