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.

Nikolaj Bjorner 7aa4fc2d8f fixing #5164 
overloading resolution has evolved a bit given how it inter-operates with automatic insertion of coercions, instantiation of polymorphic data-types, arrays as function spaces and other goodies. This is a rewrite of overloading resolution to disentangle the main components and allow them to cascade to give room for each-other.

underlying issue is that model updates for multi-objective and single objective solving are too brittle to serve its use cases among different plugins.
For maxlex, the last model is always the best and it doesn't use multiple objectives.

zstring: fix encode rountrip for '\' as printable ASCII (#5120) 
This fixes encode roundtripping for all printable ASCII characters.
In particular, this now leaves a plain '\' untouched by the
encoding logic, instead of converting it to escaped hex-digits.
It also adds unit testing covering this specific zstring encoding
property, in order to avoid future regressions.
