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

188a478214 #5417 
strict inequality (over reals) require solving for least-upper/greatest-lower bounds that may coincide with non-strict inequalities (be epsilon stronger). Instead of using the coefficient 'a' to turn the inequality into an equality, add the slack value as a constant.
