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.

The authgraph_hal library should only depend on libauthgraph_wire, not
on libauthgraph_core, so adjust error processing accordingly.

Add an implementation for the AuthGraph key exchange HAL, to allow
testing and policy compliance.
In real use, IAuthGraphKeyExchange instances are expected to be
retrieved from some other HAL, allowing the AuthGraph instance to be
specifically correlated with the component that uses it.
