[LayoutNG] Fork UpdateVisualRect loop for when selected

As Finch indicated pre-paint is slower in NG, this patch
splits the loop to compute VisualRect for fragments for when
there's a selection for the LayoutObject and for when not.

By splitting the loop, not only reducing the work within the
loop, we could try to apply simplication of VisualRect for
inline fragments as legacy does.

For the branch when there is a selection, yoichio@ will look
into it after the end of January.
