Added the MagicLeapInputSimulator prefab to provide Magic Leap input simulation (e.g. Controller) when playing in the Unity Editor.
To use the Magic Leap input simulator, either enable the settings option to automatically add it in Editor play mode, in Edit > Project Settings > MRTK3 > Magic Leap Settings,
or manually place the prefab in the scene. The prefab is located in /Runtime/Common/Simulation/Prefabs/.
Updated the StereoConvergenceDetector to use the new MagicLeapEyeTrackerFeature when using OpenXR and Magic Leap Unity SDK 2.4.0 or greater.
