Revert "Remove GraphicsLayer::SetNeedsDisplay()"

This reverts commit 80a372d91c63d6da3471206cec49027b72a61e6f.

Reason for revert: To diagnose performance regressions.

Original change's description:
> Remove GraphicsLayer::SetNeedsDisplay()
>
> With unified PaintController, to support SetNeedsDisplay() we would
> need to add PaintController mechanism to invalidate all display items
> in a range for a GraphicsLayer. Removing SetNeedsDisplay() can avoid
> that. We instead use the normal paint invalidation code path. For
> needed invalidation, now invalidate the display items of and in the
> GraphicsLayer. Some invalidations are not needed because we have
> already invalidated the DisplayItemClients.
>
> Also rename SetContentsNeedsDisplay() to InvalidateContents(), and
> SetNeedsDisplayInrect() to InvaldiateRaster() which is only called by
> RasterInvalidator.
