This causes video corruption when swap chain is resized to a small size
and then resized back to a large size.  If the swap chain doesn't update
after resizing back, it will remain with the smaller size.

It's also likely that this causes video corruption issues with minimize
and restore, and with the Aero peek live preview Windows feature.

Split out from crrev.com/1305198 because that change is more risky and
we want to wait until M72 branches to land it.
