rob thijssen 2480d7828b Cache CUDA context and module in CudaEngine for reuse 
Initialize CUDA context and load module once per engine instance,
storing them in a mutex-protected cache to avoid repeated setups. Use
cached context/module for kernel launches, creating a fresh stream each
call. Adjust grid dimension calculation to consider multiprocessor
count.
