### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary: File scanner v2 reads Parquet through Arrow, so the old
vparquet page cache path is not used. Repeated scans still go through the Doris
file reader for serialized Parquet column chunk data even when the Parquet page
cache option is enabled. This change registers the selected Parquet column
chunk byte ranges after row-group planning and lets the Arrow RandomAccessFile
adapter reuse StoragePageCache for reads inside those ranges. Footer and
metadata reads happen before range registration and are intentionally excluded.
