> Add kernel exec generator for string binary functions (similar to
> StringTransformExecBase) that always expect the first parameter to be of
> string type and the second parameter is generic. It should also support
> scalar and array inputs for the following common cases:
> * Scalar, Scalar
> * Array, Scalar - scalar is broadcasted and paired with all values from array
> * Array, Array - process arrays element-wise
> The Scalar, Array case is not necessary as it is difficult to generalize, and
> there are not many functions with this pattern.
