remove m_b from lar_core_solver
...
the column vector is pure overhead for the way the lar solver uses lp.
Some other solver modules use column vectors b and integrate with the lp_core_solver_base. The interaction model should be reviewed.
Unused solvers should be removed to make it easier to maintain this code.

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

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.
