Is your feature request related to a problem or challenge? Please describe what you are trying to do.

We only have powf_scalar, modulus_scalar and divide_scalar. We need more mathematics kernels for array and scalar value that could be used by downstream projects e.g. datafusion.

Describe the solution you'd like

thank you @viirya
I'm implementing some mathematics operation for decimal data type in datafusion, and finding the enhancement for arrow-rs kernel.
