[M123] Toggle NTP Wallpaper Search button w/ Wallpaper Search setting

1. Toggles visibility of NTP Wallpaper Search button whenever
   its setting is changed. *video demo in bug comments

We add SettingsEnabledObserver [1] to new_tab_page_handler.cc, and
communicate changes to settings via Mojo to the renderer.

2. Restructures wallpaper_search_interactive_uitest.cc into two
   test suites. *The only "new" test is
  |NTPWallpaperSearchButtonVisibilityDependsOnSettings|.

Setting changes are not observed if MockOptimizationGuideKeyedService is
being used [2], so we create a separate suite for tests that rely on
MockOptimizationGuideKeyedService.
