[RasterInducingScroll] Force update even without raster invalidation

The following changes won't cause raster invalidation:

• A scroller is added/removed without any visible change;
• Some scrolling content out of a non-composited scroller's
  scrollport changes.

Previously we skipped cc layer update because nothing visible
changed. However, future raster-inducing scroll without
main-thread update could scroll the out-of-date content into
view.

Now force update in RasterInducingScroll in
ContentLayerClientImpl::UpdateCcLayer().
