Experiment with allowing tap to break through to interact with the PIP.

Test: Enable SysUI tuner, tap once on PIP to interact with the activity.
      This is only experimental behaviour, and
      android.server.cts.ActivityManagerPinnedStackTests will be updated
      accordingly if we keep this behavior.
