Fix CROSS JOIN crash and LEFT JOIN filter pushdown

- Fix CROSS JOIN and NATURAL JOIN NullReferenceException when join
  has no ON clause (null constraint handling in parser and plan)
- Fix LEFT JOIN filter pushdown: WHERE filters on the null-supplying
  side were incorrectly pushed past outer joins, producing wrong
  results. Add fromUserQuery_ flag on LogicJoin to distinguish
  user-written joins from subquery decorrelation joins
- Add pushdownSingleTableFilter that respects outer join boundaries
- Improve GROUP BY validation with stale ExprRef detection
