Reviewed by Adrienne Walker.

Source/Platform:

This changes WebLayer from a value type to a pure virtual interface and changes Web*Layers from subtypes to
standalone types that have a WebLayer. This better isolates the implementation from the interface and, since
it's not possible to re-wrap an existing layer, makes cleanup explicit instead of requiring the caller to invoke
special cleanup methods before shutdown.

Source/WebCore:

This updates WebCore code for the WebLayer interface changes. Classes that have ownership of specific layer
types (such as DrawingBufferChromium, Canvas2DLayerBridge and ScrollingCoordinatorChromium) hold ownership
of a specific type and a pointer to the WebLayer to GraphicsLayerChromium to be included in the final layer
tree. GraphicsLayerChromium holds a WebContentLayer and (optionally) a WebImageLayer and WebLayer (for
m_transformLayer) and assembles the final layer tree.
