Search experience improvement for large screen

- Support fragment and direct link in SearchResultTrampoline
- Start activity for SI case and start deep link trampoline for others
- Disable menu highlight whenever the search bar is clicked
- Don't overwrite SettingsApplication's homepage activity in
  SliceDeepLinkHomepageActivity
- Scroll to highlighted menu entry after homepage is loaded to prevent
  UI overlapping
