AuthGraph: move code into library
Use the core library's new service implementation, which wraps a
channel to the TA.
In this nonsecure case, the TA is local in-process, so use the core
library's AuthGraphTa, and implement the SerializedChannel as just
a direct invocation of the TA.
Move this code into a _nonsecure library, so the main.rs just has
the code needed to start the executable and register the service.
