[anchor-position] Support anchors on OOF boxes

This patch supports anchors on OOF boxes inside of a block
fragmentation context.

To do this, this patch:
a. Enables per-containing block layout of OOFs if they have
anchors.
b. Find laid out OOFs with anchors and add them to anchor
queries of their containing block chain.

This patch doesn't support anchors on in-flow boxes inside of
OOF yet. This needs to look into all children of OOFs, or
propagate a flag while style recalc, but unfortunately there
are no spare bit flags in |LayoutObject| as of today. How to
do it without a flag, or how to add a flag, is deferred to
future patches.
