Structured bindings were not properly marked odr-used
and therefore captured in generic lambddas.

Fixes #57826

It is unclear to me if further simplification can be gained
through the allowance described in 
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0588r1.html.

Either way, I think this makes support for P0588 completes,
but we probably want to add test for that in a separate PR.
(and I lack confidence I understand P0588 sufficiently to assert
the completeness of our cnformance).
