[I] [C++] A more efficient implementation for list-view types in case_when and coalesce kernel functions [arrow]

ZhangHuiGui opened a new issue, #41453:
URL: https://github.com/apache/arrow/issues/41453

   ### Describe the enhancement requested
   
   Enhancement comes from: https://github.com/apache/arrow/pull/41419#discussion_r1583854772.
   The list-view types should have their own specialization in these two functions.
   Because they have a super-power that classic list types don't have: you can append the child values in any order and adjust the offset/size pairs of any random position to point to that area.
   
   ### Component(s)
   
   C++
