blink: Ensure overflow clip and visible have consistent behaviour.

This includes the following set of changes in preparation to add
overflow:clip to all img elements in UA CSS. The aim is to have
consistent behaviour between overflow:visible/clip for the following
layout cases:

  • Use min size:auto when overflow:clip is used on a child element with
    the ancestor using grid layout.
  • Don't synthesize logical baseline for overflow:clip similar to overflow
    visible. See https://github.com/w3c/csswg-drafts/issues/6212 for
    context.
  • When using spatial navigation, consider the topmost paint layer which
    has no self painting visible descendents instead of all visible
    descendents. This accounts for paint layers created for overflow which
    are for bookkeeping purposes and don't change the paint order.
