[C++][Parquet] onsolidate RecordReader, ColumnReader code paths #42865
Description
The record-delimiting logic is central to reading nested data from columns. When RecordReader was created, I duplicated quite a bit of logic from column_reader.h, and never got around to refactoring further. We'll have to be careful about preserving backwards compatibility for flat column reads, though
