Revert of cc: Re-use transforms from transform nodes when computing visible rects

Revert of cc: Re-use transforms from transform nodes when computing visible rects (patchset #2 id:20001 of https://codereview.chromium.org/1060413002/)

Reason for revert:
Causes css3/filters/effect-reference-hidpi-hw.html to have an incorrect visible rect.

Original issue's description:
> cc: Re-use transforms from transform nodes when computing visible rects
>
> This makes CalculateVisibleRects try to re-use the to_target and
> from_target transforms stored in transform nodes whenever it needs to
> compute a transform. Since these baked transforms incorporate the
> target's sublayer scale, the fallback path now also includes sublayer
> scale for consistency.
>
> Testing locally on a z620, this improves property tree computation time
> by 7% on Gmail, and by 20% on rAF-driven poster circle.
