Don't use icon home animator when entering PIP

- If the app supports pip, can just do the fallback workspace
  home animation since the app will not be going to the icon

Bug: 190464560
Test: Open YT, swipe up, ensure it goes to the icon,
      Reopen YT video, swipe up, ensure it goes into PIP without
      icon animation
