feat: Add combinatorial reasoning as a component (#4782)

* Add Icosa's Combinatorial Reasoner as component under tools

* Remove temporary testing tool revert unit test script

* reverting changes to locks

* [autofix.ci] apply automated fixes

* [autofix.ci] apply automated fixes

* Moved combinatorial reasoner component to separate icosacomputing folder for Icosa's bundle
