Add append_n to bytes view builder API #9034
Description
Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Describe the solution you'd like
Want an API on byte view builders that allow appending N identical values. See DataFusion PR for context: apache/datafusion#19441
Describe alternatives you've considered
Currently DataFusion needs to use a builder with deduplication enabled and append in a for loop, which requires hashing the bytes each time to ensure deduplication works.
