use correct pointer type for CUdeviceptr on aarch64 in nvdec filter

This fixes the following warnings:
```

These became errors in GCC 14. Note: `CUdeviceptr` was already defined to
`long long unsingned int *` on aarch64:
https://github.com/gpac/gpac/blob/master/src/filters/dec_nvdec_sdk.h#L59
but the condition enabling the use of 64-bit pointers was missing in
other places.
