[block-in-inline] normalChildNeedsLayout() with no child marked for layout
should not trigger fast path (layoutSimpleBlockContentInInline)

Reviewed by Antti Koivisto.
Although renderer->setChildNeedsLayout() is intended to signal that an in-flow
child of this renderer needs layout,
in practice it is used to force a self-layout on this renderer, much like
calling renderer->setNeedsLayout().
(it's usually called by passing in 'MarkOnlyThis'.)
setChildNeedsLayout is heavily used in table layout e.g. after setting
intrinsic padding on the cell renderer.
RenderBlockFlow's layoutSimpleBlockContentInInline is meant to handle content
where the block child itself needs layout and not the container.
