How do I know maxContexts for ffxGetScratchMemorySizeDX12?

For example, for FSR3Upscaler.

Maybe:

    typedef enum Fsr3BackendTypes : uint32_t
    {
        FSR3_BACKEND_SHARED_RESOURCES,
        FSR3_BACKEND_UPSCALING,
        FSR3_BACKEND_FRAME_INTERPOLATION,
        FSR3_BACKEND_COUNT
    } Fsr3BackendTypes;

            int effectCounts[] = {1, 1, 2};
            for (auto i = 0; i < FSR3_BACKEND_COUNT; i++)

So, 1 for FSR3Upscaler.

Thanks.
