Extend #234 (Goto<T>) to CreateMachine etc.

[TedHartMS]

Copied from #238 (resolving #234):

PSharpRuntime has several methods that take (Type type, ...):

• the CreateMachine variants
• RegisterMonitor
• InvokeMonitor This is the only one that also has a generic overload: InvokeMonitor<T>(Event e).
• also INetworkProvider.RemoteCreateMachine

Add the generic form for these and deprecate the non-generic form.
