Support returning .NET 5 threads to ObjC

[ghost]

My .Net class library that I want to embeddinate contains two simple threads that I start.

Steps to Reproduce

1. Build VB IOS class library .Net Standard project on Mac
   My .NET IOS class lib starts two threads...............

		Imports System.Threading
		Imports System
		Imports System.IO

		dim RF_glucose_Thread as thread
		RF_glucose_Thread = new Thread( AddressOf RF_glucose_executive )
		RF_glucose_Thread.Name = "RF GLUCOSE ALG"
		RF_glucose_Thread.Start()		

		public embedded_communication_thread as thread
		embedded_communication_thread = new Thread( AddressOf run_acquisition_session )
		embedded_communication_thread.Name = "COMM RF HW"
		embedded_communication_thread.Priority =  std.RF_HW_COMMUNICATION_THREAD_PRIORITY
		embedded_communication_thread.Start()				

2. Run objcgen to generate ObjC from .Net

Expected Behavior

ObjC generation of threading used within library

Actual Behavior

objcgen outputs:
error EM0009: The feature Returning type Thread from native code is not currently supported by the tool

Environment

.Net Standard 2.0

The tool does not support passing threads to Objective-C, as we'd have to bind all of the API you can invoke on threads as well.

You should be able to create a wrapper with a limited subset of functions (and it not public).

I'll keep this open as a feature request.
