ARROW-16035: [Java] Handling empty JDBC ResultSet

ArrowVectorIterator.hasNext() delegates to the underlying resultset.isAfterLast() method, but per JDBC specs, this [should return false in the case of empty ResultSets](https://docs.oracle.com/en/java/javase/11/docs/api/java.sql/java/sql/ResultSet.html#isAfterLast()).  This causes hasNext() to return true for empty ResultSets, triggering infinite loops.

Closes #13049 from toddfarmer/tofarmer/fix-hasnext-for-empty-resultset
