   Will comment more later. One thing I want to note is that resource handle is a special thing for PackedCFunc signature and do not generally exists in a normal packed func(that is backed by say a GPU driver closure). 
   
   As a result, we might want to think a bit more carefully on the calling convention here. My recommendation would still be try to hide this variables from the PrimFunc interface and leverage intrinsics(such as get resource handle) to obtain the handle from the environment. 
   
   We might be able to introduce call packed c func with handle intrinsic that passes the handle around packed c func
