Overview

Unity 2023.1 introduce await support for pretty much every async constructs in Unity. As an example we added a GetAwaiter extension method to AsyncOperation.
This introduce ambiguous calls at compile time when trying to compile the MRTK package because of this file here: https://github.com/microsoft/MixedRealityToolkit-Unity/blob/0d2cdf9defe019ad8cdf1093bb8580c646e9695e/Assets/MRTK/Core/Utilities/Async/AwaiterExtensions.cs

Note: I'll try to submit a PR next week to fix this

Expected behavior

With 2023.1+, those extension methods should not be compiled, and the code relying on them should use Unity-builtin awaiters

Actual behavior

Compilation of the package fails

Steps to reproduce

• Create a project with Unity 2023.1
• Add the package to it
• Compilation fails
