StackTraces are missing for exceptions when using IL2CPP and .NET 4.x runtime. By switching to .NET 3.5 runtime StackTraces are printed normally

To reproduce:

1. Download attached project "AndroidStacktraces.zip" and open in Unity
2. Open "SampleScene" scene
3. Set Android platform
4. Go to Player Settings > Other Settings and change Scripting Runtime Version to Stable (.NET 3.5 Equivalent) and set Scripting Backend to IL2CPP
5. Build and run the project on an Android device
6. Press "Crash" button and observe Stack trace is printed normally
7. Go to Player Settings > Other Settings and change Scripting Runtime Version to Stable (.NET 4.x Equivalent) and set Scripting Backend to IL2CPP
8. Build and run the project on an Android device
9. Press "Crash" button and observe that there is no Stack trace
