Revert of Snap RWHVA and resize the legacy window on Windows whenever the ancestor window's bounds change. (patchset #12 id:220001 of https://codereview.chromium.org/1062273002/)
Reason for revert:
Speculative, possibly caused lots of browsert_tests redness on a bot that runs browser_tests with an official build (and a different compiler, but all the redness we fixed on official builds so far were caused by the builds being official, not because of the compiler): http://build.chromium.org/p/chromium.fyi/builders/CrWinClang%20tester/builds/285 (see http://crbug.com/467929)
Original issue's description:
> Snap RWHVA and resize the legacy window on Windows whenever the ancestor window's bounds change.
>
> The bookmark bar is hidden through the fast resize code path where in the Renderer is informed about
> the actual size minus the bookmar bar before the bookmark bar is hidden. To ensure that the RWHVA is snapped
> to pixel boundaries and the legacy window is resized we observe bounds changed events on the parent of the WCVA
> window which is the NativeViewHost clipping window. Reason for doing this is the layer for the window hosted by WCVA
> verifies if the stored bounds is the same as the one coming in and ignores the change if yes.
