This bug was introduced by SPARK-30428 at Apache Spark 3.0.0. This PR fixes `FileScan.equals()`. - Without this fix `FileScan.equals` doesn't take `fileIndex` and `readSchema` into account. - Partition filters and data filters added to `FileScan` (in apache#27112 and apache#27157) caused that canonicalized form of some `BatchScanExec` nodes don't match and this prevents some reuse possibilities. Yes, before this fix incorrect reuse of `FileScan` and so `BatchScanExec` could have happed causing correctness issues. Added new UTs. Closes apache#31848 from peter-toth/SPARK-34756-fix-filescan-equality-check.
