Two optimizations:
std::unordered_mapto reduce lookup time, which could be significant where the number of inputs is largevectorto track the corresponding input arg dltensor* so we don't need to iterate through the inputs of all notes to look them up every single time. This is a followup to [Runtime] Enable set_input_zero_copy in GraphRuntime #3416@yinghai, @tqchen please review
