Subject: feat(dependency-resolver): share policy via Rc, drop clone_box

PolicyInterface::clone_box (a todo!() trait-object clone stub) is removed
in favor of Rc<dyn PolicyInterface> shared ownership, matching PHP's
by-reference sharing of the single $policy object across Solver,
RuleSetGenerator and PoolOptimizer. With PoolOptimizer::new now taking an
Rc, Installer::create_pool_optimizer is implemented faithfully
(return new PoolOptimizer($policy)); create_policy returns the shared Rc.
