[LayoutNG] Fix for incorrect Legacy containing block oof removal
When containing block changes from being an OOF container
to not being one, it needs to remove the positioned descendants
from its list of positioned objects.
If an OOF object remains in the positioned objects list,
it will cause NGOutOfLayoutPart::SweepLegacyDescendants
to go into an infinite loop and run out of memory. This
was fixed to just trigger a DCHECK in a recent CL.
LayoutInline::StyleDidChange did not perform OOF descendant
removal correctly. LayoutInline OOF descendants are stored in
first non-anonymous block on parent chain, (container's container)
which is not the same as ContainingBlock().
Added a method that computes container's container to
LayoutObject, and made LayoutInline call it.
This fix also works for fixed, because
fixed containers are always absolute containers.
