[Fix](multi catalog, nereids)Fix text file required slot bug (apache#…

…20214)

required_slots in TFileScanRangeParams params for external hive table may be updated after FileQueryScanNode finalize. For text file, we need to use the origin required_slots in params so that the list could be updated later. Otherwise, query text file may get the following error:
[INTERNAL_ERROR]Unknown source slot descriptor, slot_id=3
