Summary Layer tree unfreezing and rendering update scheduling need to work together

We currently rely on timers to trigger style updates/render tree updates, and this is necessary to trigger unfreezing the layer tree (via visually empty threshold). Ideally the style system would not have any of its own timers; it would just schedule rendering updates. However, TiledCoreAnimationDrawingArea::triggerRenderingUpdate() just bails if the layer tree is frozen. We need to somehow harmonize layer tree freezing with rendering updates.
