[BlackBerry] Find a proper fix for the WebPagePrivate::enqueueRenderingOfClippedContentOfScrollableNodeAfterInRegionScrolling hack

We've generalized composited in-region scrolling, originally only applicable
to block elements, to inner frames (see PR #197093). Past that, we no longer
need to force repaints of offscreen areas when we finish scrolling, since translating
the Layer takes care of properly invalidating it. Thus, remove this method.
