NVIDIA cuDNN Backend

Use the NVIDIA cuDNN backend API only if you want to use the legacy fixed-function routines that are not graph-based interfaces and are not exposed by the frontend API layers.

The NVIDIA cuDNN frontend API provides a simplified programming model that is sufficient for most use cases.
