What changes were proposed in this pull request?
An ORC file written by an old version has no field names in the physical schema. To read it, we must map table schema to file schema using indices.
ScanTransformer#getDataColumnsas table schema to Velox.This PR depends on facebookincubator/velox#12489 (old ORC files) and facebookincubator/velox#12490 (match index mapping behavior in spark).
Fixed #5638.
