Ashin Gau e0667b297f [feature-wip](multi-catalog) reuse hdfsFs and decode parquet values in batch (#13688 )

PR(https://github.com/apache/doris/pull/13404) introduced that ParquetReader
will break up batch insertion when encountering null values, which leads to the bad performance
compared to OrcReader.
So this PR has pushed null map into decode function, reduce the time of virtual function call
when encountering null values.

Further more, reuse hdfsFS among file readers to reduce the time of building connection to hdfs.
