GB3-1715: arrow navigation in search

[TIL-EBP]

This PR adds new directives that allow keyboardnavigation through search result on the map page and the start page.
One directive handles all the keyboard events, the highlighting of the selected result etc.
The other one is just there to mark search results so they can be reached via arrow keys. This are passed via ViewChildren and VieChild to the respective container,

For this, some adaptations were made to the results:
They are now fully clickable, not just the icons.
The tab navigation has been romved from many elements in order not to conflict with the arrow navigation.

Testing will be added asap

Hey Till, sorry I couldn't finish the review yet. But from what I saw yet I cannot approve this requests. There are currently some show stoppers in the frontend.
As for the code: I'll have a look into that probably on Monday. Maybe we'll find some time when you can give me an overview of the changes and your thoughts.

[wendlans]

I'm happy with the results but what did it cost? 😅

Maybe let @Tugark have a second look at the base-search-container.component.ts.

[Tugark]

I had a look at base-search-container as @wendlans suggested.

I see that there is a lot of black magic going on, so have my approval 👍

On a more serious note: Can you have a look at the duplication warnings by Sonar and if possible, reduce/fix them? If not, head over to SonarCloud and set their status (e.g. false positive, or acknowledged-WONTFIX). If you can't log in, you maybe don't have rights, but I think we could provide them to you. That way, you would not have to bypass rules.

@Tugark I looked at the duplications and it's just the super-calls from the child components to the newly created parent compoennt base-search-container.component.ts.
So I think we can mark them as false positive. But you are right, I do not have permissions to do so (at least not with my github account).
