…#167111) cuDNN dispatching heuristics rely on versions checks but currently only that compile-time version is exposed, if we want to allow users to resolve #166643 on their end by updating their cuDNN version locally we need to check the runtime version rather than compile-time version.

cuDNN dispatching heuristics rely on versions checks but currently only that compile-time version is exposed, if we want to allow users to resolve #166643 on their end by updating their cuDNN version locally we need to check the runtime version rather than compile-time version.
Test plan: add test comparing performance with cuDNN 9.15+ when disabling and enabling convolutino explicilty for 3D cases.
