### Is your feature request related to a problem or challenge? The current `array_concat` implementation does a lot of unnecessary copying, and calls the Arrow `concat` kernel twice. This could be simplified, following a similar approach to that used in #19996 for `array_remove` -- read list offsets directly and use `MutableArrayData::extend()` to copy element ranges in bulk ### 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.
