Which issue does this PR close?

Closes #2369

Rationale for this change

Fix some ORC predicate pushdown with OR losing data.

What changes are included in this PR?

  • Made OR pushdown all-or-nothing: collect_or_predicates now returns bool, and if any disjunct fails to convert, the whole OR is not pushed down (convert_expr_to_orc returns None). Convertible AND conjuncts
    around the OR still push down safely.
  • Added unit tests covering: OR with an unconvertible disjunct, OR whose disjunct is a fully-unconvertible AND, and an unconvertible OR nested in an AND where the sibling conjunct still pushes down.

Are there any user-facing changes?

no
