Polysat disjunctive lemmas (WIP) (#5275)

Browse source 
* Extend search state by boolean literals

* Only resolve against positive equality

* mk_dep_ref

* Make clause non-owning

* scoped_clause

* Use scoped_clause

* minor

* scoped_ptr move assignment

* WIP: internal handling of disjunctive constraints

* leaf_value

* disjunctive constraints continued

* Fix bool_lit

* Actually add constraints to storage

* Some fixes

* more fixes

* constraint should have a bool_lit instead of a bool_var

* propagate(bool_lit)

* updates

* interface changes

* small fixes

* Make sat::dimacs_lit's constructor explicit

(otherwise, calling operator<< with sat::literal is ambiguous)

* Use sat::literal

* Print test name at the beginning

* Convention: constraint corresponds to the positive boolean literal

* Make constraint ownership more explicit

* clause stores literals
