Andrew Scott d8cf78ba5e fix(router): Do not call preload method when not necessary (#47007)
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.
