### Is your feature request related to a problem or challenge? `array_sort` currently invokes an Arrow kernel for every row and assembles the results. While #21006 makes this a bit faster, it is still relatively slow. If we instead wrote a custom sort kernel that operates on the entire ListArray and sorted it directly into a preallocated output buffer, that would likely be much faster. Idea per @Dandandan in #21006 ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
