1. fix(router): Do not call preload method when not necessary …

   In Angular 14, we introduced the `loadComponent` API for a `Route` to
   allow lazy loading of a routed component in addition to the existing
   `loadChildren` which allows lazy loading of child routes. As a result,
   the `preload` method of the `PreloadingStrategy` needs to sometimes be
   called even when there is a `canLoad` guard on the `Route`. `CanLoad`
   guards block loading of child routes but _do not_ block loading of the
   component.
   
   This change updates the conditional checks in the internal preloader to
   skip calling the `PreloadingStrategy.preload` when there is only a
   `loadChildren` callback with a `canLoad` guard an no `loadComponent`.
   In this case, the callback passed to the `preload` method is already
   effectively a no-op so it's not necessary to call it at all.
   
   resolves angular#47003
