cc: Remove LayerTextureUpdater::Texture::updateRect() callback.

This is the first step towards cleaning up and simplifying the resource
update system. Eliminates the LayerTextureUpdater::Texture::updateRect()
callback by moving some logic to CCResourceProvider. Remaining logic is
now contained in LayerTextureUpdater::Texture::update(). The logic itself
is not changed, this is only re-factoring.
