Create an InvokerEnt around a single function.

Syntax:

  invoker_ent!( function )
  invoker_ent!( @special function )

The function must be a fn item (with all necessary generic parameters specified) with the correct type for an RPC implementation function; see the module documentation.

If the function is marked as @special, it does not have to return a type serializable as an RPC message, and it will not be exposed as an RPC function. You will still be able to invoke it with DispatchTable::invoke_special.
