Fix after changes made in #568
torch.compile doesn't like returning input arguments. So, change the return type of pybind fns to
void, given that it's already an inplace op.PyTorch Library annotation is applied to a wrapper function for each pybind op. Python API doesn't change. Both inplace and non-inplace versions calls the annotated wrapper function.
