perf(advanced-search): span-based leaf evaluator for EvaluateBoolean

Browse source 
Custom LeafEvaluator<TState> delegate takes the leaf as ReadOnlySpan<char>
(Func<> can't take a ref struct) and threads caller state through, so the
property-test recursion allocates neither a per-leaf string nor a capturing
closure per entity.
