Reviewed by David Hyatt.

This patch extracts layer-related logic into a dedicated class
(RenderLayerModelObject) and refactors dependent code to make use
of the new type instead of RenderBoxModelObject. This is in preparation
of adding non-RenderBoxModelObject layer supprt.

All methods that were using RenderBoxModelObject for layer-related
functionality are updated to work with RenderLayerModelObject
instead (a RenderLayer's renderer() can no longer be assumed to be
a RenderBoxModelObject).

No new tests: refactoring with no behavior changes.
