Fix Ocaml bindings FuncEntry to_string (#6639) 
Hello, I was looking at the different api string conversions for FuncEntry and I believe that the ml version is incorrect? Clearly we want the argument(`c`) to be comma separated from the accumulated string `p`. The current implementation just so happens to have most of the arguments separated, but the order is flipped and one of the commas is misplaced.

Documentation on how to add z3 to CMake project using FetchContent and documentation to recdef function. (#6613) 
* Added overloaded versions of context::recfun in the c++ api that allow for the declaration of recursive functions where the domain is given by a z3::sort_vector instead of an arity and sort*

* added documentation to recdef function

* added a section in the README-CMake.md that explains how z3 can be added to a CMake project as a dependency

Nikolaj Bjorner 0758c93086 fix #6591 
- add check for lambdas similar to as-array in context of quantifiers. MBQI is not a decision procedure for this combination and can then incorrectly conclude satisfiabiltiy.

Scenario

The formula contains assertions
 - bv = (map or (lambda ..) t)
 - forall y (not (select bv (pair s y)))

Since bv is extensionally equal to a term that depends on a lambda, MBQI cannot just take the current finite approximation of bv when checking the quantifier for satisfiability.

Nikolaj Bjorner 6022c17131 Add simplification customization for SMTLIB2 
Add the ability to customize incremental pre-processing simplification for the SMTLIB2 front-end. The main new capability is to use pre-processing tactics in incremental mode that were previously not available. The main new capabilities are
- solve-eqs
- reduce-args
- elim-unconstrained
There are several more. Documentation and exposed simplifiers are populated incrementally. The current set of supported simplifiers can be inspected by using z3 with the --simplifiers flag or referring to https://microsoft.github.io/z3guide/docs/strategies/simplifiers

Some pending features are:
- add the ability to update parameters to simplifiers similar to how tactics can be controlled using parameters.
- expose simplification solvers over the binary API.

It also consolidates some of the backtracking state in nla_core / emons to use stack traces instead of custom backtracking state.
