[LayoutNG] Fix overflow:scroll inline-block painting

display:inline-block with text children gets painted as AtomicInline.

NGBoxFragmentPainter::PaintAllPhasesAtomically was setting overflow
clip for all painting phases, cutting off anything outside content box.
It also was not painting scrollbars.
