Polysat: use constraint_literal and begin move to core-based conflict representation (#5489) 
* Rename solver_scope for fixplex tests

(otherwise the wrong constructor is called for polysat's solver_scope)

* Update conflict_core

* simplify

* Be clearer about constraint_literal lifetime

* remove old comment

* Remove status (positive/negative) from constraint

* Use constraint_literal in the solver

* Fix build (constraint -> get_constraint)

Polysat updates (#5444) 
* Simplify adding lemmas

* Remove misleading constructor from tmp_assign.

The idea is that tmp_assign is only created on the stack and
short-lived.  Instead of having a convenience constructor that takes a
constraint_ref, it's clearer to have an explicit .get() at the call
site.

* Remove some log messages

* bugfix

* fix

* Add stub for conflict_core

* wip

* Add example by Clemens
