### Is your feature request related to a problem or challenge? As noted in the discussion in https://github.com/apache/datafusion/pull/11941#discussion_r1713604384 it looks like the performance of the lpad udf may be improved a bit by using a GenericStringBuilder instead of creating a string every time. As well, as noted in https://github.com/apache/datafusion/pull/11941#issuecomment-2284011527 there may be room for improvement with the general code. ### Describe the solution you'd like lpad udf updated to use a GenericStringBuilder and a benchmark added to showcase whether it improves performance or not ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
