Implement search feature (#685)
Implement search feature - Add a feature module named "search" - Add a SearchScreen that is navigated by tapping the search icon at the top left corner - Add a data layer that takes care of populating the *Fts tables and querying them by a search query - Add a SearchViewModel that wires up the data layer of the Fts tables with the SearchScreen The SearchScreen has following features: - The user is able to type the search query in the TextField - The search result is displayed as the user types - When the search result is clicked, it navigates to: - The InterestsScreen when a topic is clicked - Chrome custom tab with the URL of the clicked news resource - When the search result is clicked or the IME is explicitly closed by the user, the current search query in the TextField is saved as recent searches - Latest recent searches are displayed in the SearchScreenpull/689/head
