Translate the taskbar icons to match nav handle shape.

- We need to reset icon alignment whenever icon layout bound
  changes. This fixes the issue where we build an icon
  alignment animator before any of the views are laid out.
- Separated animation logic between.
  createTransientAnimToIsStashed and createAnimToIsStashed
* The values still require a bit more tuning but this gets us
  a lot closer to spec for many of the motion polish.
