   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   A clear and concise description of what the problem is. Ex. I'm always 
frustrated when [...] 
   (This section helps Arrow developers understand the context and *why* for 
this feature, in addition to  the *what*)
   We are working on adding a `power` function / operator to datafusion 
(https://github.com/apache/arrow-datafusion/issues/1493).  Rather than 
implementing in datafusion i propose adding it as a compute kernel in arrow 
because we can implement directly with rust float primitives 
(https://doc.rust-lang.org/std/primitive.u32.html#method.pow, 
https://doc.rust-lang.org/std/primitive.f32.html#method.powf, etc) without any 
additional logic, similar to existing arrow compute kernels, and this aligns 
with the C++ compute implementation 
(https://arrow.apache.org/docs/cpp/compute.html#arithmetic-functions) and 
arrow2 
(https://github.com/jorgecarleitao/arrow2/blob/main/src/compute/arithmetics/basic/pow.rs)
   
   **Describe the solution you'd like**
   `power` (using two arrays) and `power_scalar` (array and scalar) compute 
kernels
   
   **Describe alternatives you've considered**
   A clear and concise description of any alternative solutions or features 
you've considered.
   
   **Additional context**
   Add any other context or screenshots about the feature request here.
