Summary Track SVG renderer updates using a NodeFlag instead of on Style::Update

SVG renderer updates are currently tracked as a kind of Style::Update change. When a page is updating attributes on many SVG elements, but is not making changes that require a restyle on those elements, we can spend a lot of time hashing to store and look up the Style::Update associated with an element. We could track the "SVG renderer update is needed" state using a Node flag instead, but continue using the Style::Update mechanism for root tracking, to reduce the overhead.
