Fix paint checkerboarding over-reporting

We failed to update scrolling_contents_cull_rect on the cc scroll tree
if a scroll only caused repaint but not a full PaintArtifactCompositor
update. The wrong cull rect caused false paint checkerboarding.

Now update scrolling_contents_cull_rect on the cc scroll tree during
PaintChunksToCcLayer::UpdateLayerProperties() to ensure it is updated
for both full and repaint-only updates.
