Support `Test With > In-Proc (VS SDK)` targeting services that have been linked, not referenced

[jcansdale]

For many Visual Studio services, TestDriven.Net is able to infer the service type from the service interface when targeting a method using Test With > In-Proc (VS SDK).

For example if you target the following method:

        [STAThread]
        void ShowActiveView(IVsTextManager textManager)
        {
            ErrorHandler.ThrowOnFailure(textManager.GetActiveView(1, null, out IVsTextView activeView));
            activeView.GetCaretPos(out int line, out int col);
            Console.WriteLine($"Caret is on line {line}");
        }

It is able to find the SVsTextManager type by using the IVs -> SVs naming convention and looking for it in the same assembly as IVsTextManager or one of its referenced assemblies. It can then call IServiceProvider.GetService and pass in the returned service object.

Unfortunately this breaks down when a service interface has been embedded as opposed to reference. In this case is doesn't know where to probe in order to find the service type.
