Search screen – Android Auto

ToDo

After changed we made in #16632, that allows to access all used data from the main screen, I propose to update Search first screen.

Current	Proposed

Add step-by-step address search for Android Auto.

Select cit	Select street	Select building

• Step 1, Nearest City: Show list of nearest cities
• Step 2, Streets: show list of streets for selected city
• Step 3, Buildings: show list of buildings for selected street
• Step 4, Navigation screen with selected address

I propose to make use of the TabTemplate that comes with car-library version 1.3.0.
A maximum of 4 tabs is permitted, those could be 'Free Search', 'Address', 'Categories' and 'Favorites'.
Free-search would be default. As long there is no search-phrase it would list the recently used destinations (this is what the current searchscreen already does).

We don't how to clear or append text after you click on City, so we can't allow to have incremental search. Like type "Bos" -> select "Boston" and text field would display "Boston " or "".

@vshcherb
to clear the input just push another instance of searchscreen on the stack. This also has the benefit one can go 'back' to each previous step (both via action or hardware-button)
