Fix running of CSS Animations in SVG-in-<img>/background-image/etc.

Fix running of CSS Animations in SVG-in-<img>/background-image/etc.

Align SVGImageChromeClient with the WebViewImpl/PageWidgetDelegate/...-
cluster and call updateLayoutAndStyleForPainting on FrameView instead of
updateLayoutAndStyleIfNeededRecursive to make pending animations start
etc.

Also add a new method to DocumentTimeline to use when scheduling the
animation-timer in SVGImageChromeClient (to avoid '0' timeouts when
there's pending animations updates.)

@dstockwell, had to add a method to DocumentTimeline to check if there's any
pending animation updates. Let me know if there's any better way to achieve it.

(Thanks to a.cavalcanti/Savago for the minimized TC.)
