GetNextFrameFenceValue() always returns 1

The native rendering plugin interface functions IUnityGraphicsD3D12v7::GetNextFrameFenceValue() always returns 1.

 

To reproduce:

1. Write a native plugin that uses GetNextFrameFenceValue()
2. Use the plugin in a C# project that renders multiple frames

Expected result: The return value increase at least by one per frame

Actual result: The return value is always 1
