Making navigables responsible for backing store allocation will allow us to have separate backing stores for iframes and run paint updates for them independently, which is a step toward isolating them into separate processes. Another nice side effect is that now Skia backend context is ready by the time backing stores are allocated, so we will be able to get rid of BackingStore class in the upcoming changes and allocate PaintingSurface directly.
