Replace manual pair unpacking with structured bindings (#8197)

Browse source 
* Initial plan

* Apply structured bindings to enode_bool_pair usage

Replace manual unpacking of pairs with C++17 structured bindings in:
- src/ast/euf/euf_egraph.cpp
- src/smt/smt_internalizer.cpp
- src/smt/smt_context.cpp (2 locations)

This improves code readability and reduces boilerplate code.
