Enable contiguous check on add_i

[lhs8928]

For now checking the tensor which is contiguous or not is disabled since the add_strided does not support broadcast. Enable this one after support broadcast operation and then replace add_i or add to add_i_strided or add_strided on grucell which the operand tensor does not have a contiguous memory.
