[C++][Parquet] Non-dictionary BinaryArray reads from Parquet format have slowed down since 0.11.x

    Description

      In doing some benchmarking, I have found that binary reads seem to be slower from Arrow 0.11.1 to master branch. It would be a good idea to do some basic profiling to see where we might improve our memory allocation strategy (or whatever the bottleneck turns out to be)
