Accessibility focus should not scroll automatically.

1. We use auto scroll when a view gets accessibility focus.
   Pros: Having magnification and TalkBack enabled together (not a common use case)
         will have the accessibility focused view on the screen (it is auto panned).
   Cons: A blind user can get stuck in a very lock scroll view - not good.

2. We do not auto scroll when a view gets accessibility focus.
   Pros: A blind user cannot get stuck in a long scroll view as he has to explicitly
         scroll.
   Cons: The magnified area will not pan to ensure the accessibility focused view
         is visible.

Option one is the better trade off and this change removes the auto scrolling.
