Revert of Re-land of: Allow paint invalidation containers to cross frame boundaries.

Revert of Re-land of: Allow paint invalidation containers to cross frame boundaries. (patchset #1 of https://codereview.chromium.org/455883002/)

Reason for revert:
Broke iframe repainting: https://code.google.com/p/chromium/issues/detail?id=403734.

Original issue's description:
> Re-land of: Allow paint invalidation containers to cross frame boundaries.
> 
> The previous version had an infinite loop bug in RenderObject when there are two nested frames.
> 
> Previously, the *actual* paint invalidation container, meaning the enclosing
> compositing layer / root RenderView, could already have been across a frame boundary. The logic to do this correctly was done via special code in RenderView.
> 
> Instead, generalize the existing mechanisms to find a paint invalidation container
> and map rects to repaint container coordinate space to cross frame boundaries.
> This simplifies the code, and also causes paint invalidation rects to always be stored
> in the coordinate space of their graphics layer backing. The latter is important if we want
> to use these rects for determining which parts of a graphics layer need to be painted.
> 
> BUG=401156
