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

OperationInterface::clone_box (a todo!() trait-object clone stub) is
removed in favor of Rc<dyn OperationInterface> shared ownership. All its
methods are &self, so operations are immutable value objects that Rc can
share; pushing the same operation into multiple lists (installer's
install/uninstall splits) becomes a cheap Rc clone instead of clone_box.

Box<dyn OperationInterface> is replaced with Rc<dyn ...> across
Transaction (and its Lock/LocalRepo wrappers), Installer, PackageEvent,
InstallationManager and EventDispatcher; Box::new operation constructions
become Rc::new.
