And states should be a CuPtr, right? Feel free to directly edit this, both in libcudnn.jl and in the pointer.json (used during wrapper generation).

I cannot seem to locate the pointer.json file. Can you explain how wrappers are generated so my fixes don't disappear when we generate wrappers for the next cudnn version? I found another issue with cudnnMultiHeadAttnForward at libcudnn.jl:1991 -- the first two pointers should be CuPtrs.

I cannot seem to locate the pointer.json file.
