[margin-trim][block layout] Nested self-collapsing children at block-end
should also be trimmed.

Reviewed by Alan Baradlay.
When walking back up the block container for the purposes of block-end
margin trimming we may run into a self collapsing child that needs to
have both of its margins trimmed and its position adjusted. However, it
is also possible that these self-collapsing children may also have other
self-collapsing children nested arbitrarily within. If that is the case,
we need to also trim the margins of all of its descendants.
