feat(router): allow CanLoad guard to return UrlTree (#36610)

Browse Source 
A CanLoad guard returning UrlTree cancels current navigation and redirects.
This matches the behavior available to `CanActivate` guards added in #26521.

Note that this does not affect preloading. A `CanLoad` guard blocks any
preloading. That is, any route with a `CanLoad` guard is not preloaded
and the guards are not executed as part of preloading.

fixes #28306
