Changes from last patch:
* Moved RenderLayerCompositor::fixedPositionedByAncestor to ScrollingCoordinatorChromium. It is a chromium-specific concept that only makes sense to our implementation.
* Added WebLayerPositionConstraint, deprecate fixedToContainerLayer flag. The structure can be extended to support sticky elements at a later time.

Why not reuse WebCore::ViewportConstraints? Because our approach to fixed position layer is significantly different so there are too many parameters that are useless to us.

Chromium patch coming soon.
