Implement IAccessible2 reverse relations

Project Member Reported by nek...@chromium.org, Jun 13 2016

Issue description

The ARIA Implementation Guide define several relationships that could be present between two objects in the accessibility tree. For example, a relationship between an object and its label declared using aria-labeledby.
These relationships are bidirectional, but the reverse relationships are only required to be exposed in IAccessible2 and ATK. For example, IAccessible2 defines both the relations IA2_RELATION_LABELLED_BY and IA2_RELATION_LABEL_FOR.
Until now, we haven't implemented any of the reverse relations on Windows.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/70770adcfe2262b6886e19ac445d7c791892d011

commit 70770adcfe2262b6886e19ac445d7c791892d011
Author: nektar <nektar@chromium.org>
Date: Tue Jun 28 16:15:23 2016

Implemented IAccessible2 reverse relations.

Only ones missing are IA2_RELATION_CHILD_OF and IA2_RELATION_PARENT_OF which are used for indicating aria-owns relationships and the parent-child relationships in trees.
Since the aria-owns requirement is obsolete, the remaining part is to implement parent - child relationships in trees.

Comment 2 by nek...@chromium.org, Jun 28 2016

All IA2 relations have been implemented except for child_of and parent_of, which are not going to be implemented for aria-owns given the fact that we re-order the accessibility tree.
The only remaining work for this bug therefore is to implement child-of and parent-of for treeview controls.
