Support streaming SQL IN and NOT IN subqueries

[cjc0013]

/claim #1659

Summary

Adds streaming support for IN (SELECT ...) and NOT IN (SELECT ...) predicates by lowering top-level subquery membership checks into a dedicated two-input selection processor.

• Splits IN / NOT IN subquery predicates out of WHERE clauses while preserving residual AND filters.
• Chains multiple subquery membership predicates without changing the left-side output schema.
• Tracks right-side membership with counts, so duplicate subquery rows only change visibility on 0 -> 1 and 1 -> 0 transitions.
• Supports left and right inserts, deletes, updates, and batch inserts.
• Handles SQL NULL semantics: IN ignores NULL membership keys, left NULL keys never match, and right-side NULLs suppress NOT IN output until the last NULL is removed.
• Rejects multi-column and wildcard subquery projections, because membership predicates require one projected value.
