  Message : CL: Implement clone for kernel object clCloneKernel() can be used to make a shallow copy of a kernel object. The returned object is an exact copy of the source kernel, with latest calls to arguments sets applied to the kernel. Implement a clone version at the front-end with replicating the `clSetKernelArg` called on the source kernel. The `clSetKernelArgsSVMPointer` and `clSetKernelExecInfo` are ignored as they are currently unsupported.
