[Tizen] Add explicit dependencies on some targets.

This fixes some issues with a component=shared_library build that just
made it evident that we were using code from some parts of Chromium
without depending on the targets:

* application/browser/application_tizen.cc uses ui::PlatformEventSource.
* runtime/browser/ui/splash_screen_tizen.cc uses
  ui::ImplicitAnimationObserver.
