   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   This is part of the larger project to implement `StringViewArray` -- see 
https://github.com/apache/arrow-rs/issues/5374
   
   In https://github.com/apache/arrow-rs/pull/5481 we added support for 
`StringViewArray` and `ByteViewArray`.
   
   This ticket tracks supporting `StringViewArray` and `ByteViewArray` in the 
`cast` kernel: 
https://docs.rs/arrow/latest/arrow/compute/kernels/cast/index.html
   
   
   
   
   **Describe the solution you'd like**
   
   Specifically the following conversions should be supported in the cast 
kernels:
   * `StringViewArray` <--> `StringArray`
   * `StringViewArray` <--> `LargeStringArray`
   
   And similarly for `Binary`:
   * `BinaryViewArray` <--> `BinaryArray`
   * `BinaryViewArray` <--> `LargeBinaryArray`
   
   Notes: 
   1. Good test coverage is the most important part of this ticket
   2. I recommend 2 PRs (one for StringView and one for BinaryView) to make 
review easier -- once we have one then the other will largely follow the 
example of the first
   3. We can track other features in follow on tickets (e.g. DictionaryArray 
<--> StringViewArray)
   
   **Describe alternatives you've considered**
   
   **Additional context**
