Reset cross-db flag for each statement (#3237) (#3305)

Earlier, while parsing the batch, We were marking the all the subsequent statements of the batch as cross-database statements once we encounter any cross-database statement in batch which was incorrect. This commit fixes above behaviour by resetting 'is_cross_db' maintained at mutator level once we mark some statement as cross_db in the parse tree.
