Simon Charette a150160c9f [5.2.x] Fixed #36464 -- Fixed "__in" tuple lookup on backends lacking native support.
When native support for tuple lookups is missing in a DB backend, it can
be emulated with an EXISTS clause. This is controlled by the backend
feature flag "supports_tuple_lookups".

The mishandling of subquery right-hand side in `TupleIn` (added to
support `CompositePrimaryKey` in Refs #373) was likely missed because
the only core backend we test with the feature flag disabled
(Oracle < 23.4) supports it natively.

Thanks to Nandana Raol for the report, and to Sarah Boyce, Jacob Walls,
and Natalia Bidart for reviews.
