Revert of Add mechanism to signal DelegatedFrameHost that a surface is about to draw. (patchset #7 id:120001 of https://codereview.chromium.org/1365793002/ )

Reason for revert:
Causing memory failures on SurfaceAggregatorValidSurfaceTest.CopyRequest in cc_unittests on
http://build.chromium.org/p/chromium.memory.fyi/builders/Linux%20MSan%20Tests/builds/10514
and
http://build.chromium.org/p/chromium.memory.fyi/builders/Linux%20ChromeOS%20MSan%20Tests/builds/4653

Original issue's description:
> Add mechanism to signal DelegatedFrameHost that a surface is about to draw.
>
> This allows the FrameSubscriber to request a copy of the output even when the renderer it's subscribing to hasn't changed its contents, but a child renderer (oopif or webview) has.
