Add Azure RTOS Class A demo application LoRaWAN support

[elsalahy]

Summary:

It would be beneficial if we add LoRaWAN support to Azure RTOS

Why do we need this?

To be able to build applications supporting LoRaWAN and Azure RTOS

What is already there? What do you see now?

FreeRTOS LoRaWAN support

What is missing? What do you want to see?

Azure RTOS LoRaWAN support

How do you propose to implement this?

Create support for class A using Azure RTOS APIs (Thread creation, Delays) building on top of #165

Environment:

Azure RTOS

Acceptance Criteria:

The device is able to join the network using OTAA and sending periodic uplinks similar to freertos_lorawan

What can you do yourself and what do you need help with?

After the porting is done in #165, we need to add LoRaWAN support and this can be undertaken by one engineer.
