  -----------
  [RenderTreeBuilder] Subtree teardown should trigger repaint only on destroy root
https://bugs.webkit.org/show_bug.cgi?id=273210

Reviewed by Antti Koivisto.

1. Move repaint logic to RenderTreeUpdate so that we can issue repaint _before_ teardown.
2. Issue repaint on the destroy root and any descendants that are not part of visual overflow when needed.
