Notes:
- Project has a Native plug-in embedded, as per this manual: [https://docs.unity3d.com/Manual/WindowsPlayerIL2CPPScriptingBackend.html|https://docs.unity3d.com/Manual/WindowsPlayerIL2CPPScriptingBackend.html]
- No UnityPluginLoad seems to be called, which is supposed to happen according to this [https://docs.unity3d.com/Manual/NativePluginInterface.html|https://docs.unity3d.com/Manual/NativePluginInterface.html]
- For results of the GetFeatureLevel method it's Logged in D3D11Native.cpp. This currently returns a test value 1_0 core when not initialized at all
- In UnityPluginLoad this is set to 9_1. It's documented in [https://docs.unity3d.com/Manual/NativePluginInterface.html|https://docs.unity3d.com/Manual/NativePluginInterface.html], so the user would expect the value returned to be D3D_FEATURE_LEVEL::D3D_FEATURE_LEVEL_9_1

Resolution Note:
UnityPluginLoad and UnityPluginUnload are only called for pre-compiled native plug-ins, not for IL2CPP C++ source code plug-ins. Neither UnityPluginLoad nor UnityPluginUnload is expected to be called in this case.
