Refactor SMT core: use structured bindings for enode_pair access (#8427)

Browse source 
* Initial plan

* Refactor SMT core to use C++17 structured bindings for enode pairs

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Use const& in structured bindings to avoid copying

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Refactor variable unpacking in DEBUG_CODE
