AleksanderBodurri 5115050928 fix(devtools): DOM traversal bug (#62719)
Previously, Angular devtools would mistakenly traverse the same DOM elements multiple times while doing traversal for the component tree explorer. This error case would occur when more than 1 Angular application root component was present on the same page and in distinct DOM branches.

Some example cases that did work previously:

```html
<app-root>
...
</app-root>
```

```html
<app-root>
...
<app-root-2></app-root-2>
...
</app-root>
```

An example of where it would enter the irregular behaviour

```html
<app-root>
...
</app-root>
<app-root-2>
...
</app-root-2>
```

Now, we properly ignore duplicate DOM paths when looking for application and non-application root component to begin the Angular DevTools component discovery logic.
