Add BDD utilities; use them for narrowing/propagation of linear equality constraints (#5192) 
* Add a few helper methods for encoding sets of integers as BDDs

* Use BDD functions in solver

* Add bdd::find_int

* Use bdd::find_int in solver

* Add narrowing for linear equality constraints

* Simplify code for linear propagation

* Add test for later

* Narrowing can only handle linear constraints with a single variable

* Need to push_cjust

Add more PDD utilities (div, pow) (#5180) 
* Expose 'inv' on rationals to get reciprocal value

* Align parameter names with implementation

* Add cached operation that divides PDD by a constant

* Fix display for constant PDDs

* operator^ should probably call ^ instead of + (mk_xor instead of add)

* Add helper function 'pow' on PDDs

Cpp api general minor improvements (#5175) 
* Added noexcepts, deleted trivial copy functions that can be implcit, small things

* Add back in virtual destructor. This has rule of 5 side effects, but move semantics are not supported yet so it is *mostly* ok. The move PR will address this.
