Dmitrij Kuba d7dd2959c8 perf(router): apply prioritizedGuardValue operator to optimize CanLoad guards (#37523)
CanLoad guards are processed in asynchronous manner with the following rules:
* If all guards return `true`, operator returns `true`;
* `false` and `UrlTree` values wait for higher priority guards to resolve;
* Highest priority `false` or `UrlTree` value will be returned.

`prioritizedGuardValue` uses `combineLatest` which in order subscribes to each Observable immediately (not waiting when previous one completes that `concatAll` do). So it makes some advantages in order to run them concurrently. Respectively, a time to resolve all guards will be reduced.
