Parallel solving (#7756) 
* very basic setup

* ensure solve_eqs is fully disabled when smt.solve_eqs=false, #7743

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* respect smt configuration parameter in elim_unconstrained simplifier

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* indentation

* add bash files for test runs

* add option to selectively disable variable solving for only ground expressions

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* remove verbose output

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* fix #7745

axioms for len(substr(...)) escaped due to nested rewriting

* ensure atomic constraints are processed by arithmetic solver

* #7739 optimization

add simplification rule for at(x, offset) = ""

Introducing j just postpones some rewrites that prevent useful simplifications. Z3 already uses common sub-expressions.
The example highlights some opportunities for simplification, noteworthy at(..) = "".
The example is solved in both versions after adding this simplification.

* fix unsound len(substr) axiom

Signed-off-by: Nikolaj Bjorner <nbjorner@microsoft.com>

* FreshConst is_sort (#7748)

* #7750

add pre-processing simplification

* Add parameter validation for selected API functions

* updates to ac-plugin

fix incrementality bugs by allowing destructive updates during saturation at the cost of redoing saturation after a pop.

* enable passive, add check for bloom up-to-date

* add top-k fixed-sized min-heap priority queue for top scoring literals

* set up worker thread batch manager for multithreaded batch cubes paradigm, need to debug as I am getting segfault still

* fix bug in parallel solving batch setup

* fix bug

* allow for internalize implies

* disable pre-processing during cubing

* debugging

* process cubes as lists of individual lits
