Make Android WebView filtering depend on scrolling status.
This patch makes bilinear filtering of software images enabled only when
there is no scrolling or CSS animation active, which matches the
policy of classic WebView. In the long run, we'll likely want to support
software tiling to avoid this kind of hack, but for now this maintains
bugwards compatibility.
Most of this patch is to solve the problem that CC was not aware whether
or not WebView-handled fling is active. I added a new getter
ScrollOffsetDelegate::IsExternalFlingActive for this. This also
enables prefer-smoothness mode for these flings.
