[LayoutNG] Use ForceChildLayout() instead of ForceLayout()

ForceLayout was causing additional paint invalidations due to:
SetShouldDoFullPaintInvalidation();
...inside it.

Instead this now uses LayoutIfNeeded if the item needs layout (probably
from a style change/node removal/etc), and ForceChildLayout() which
doesn't perform this invalidation.

Fixes a bunch of paint invalidation tests.
