remove set cardinality operators from array theory. Make final-check use priority levels

Browse source 
Issue #7502 shows that running nlsat eagerly during final check can block quantifier instantiation.
To give space for quantifier instances we introduce two levels for final check such that nlsat is only applied in the second and final level.
