Revert of Implement webview.captureVisibleRegion() (patchset #9 id:160001 of https://codereview.chromium.org/1582053002/ )

Reason for revert:
The test WebViewAPITest.TestCaptureVisibleRegion is failing on several windows bots:

https://build.chromium.org/p/chromium.win/builders/Win7%20Tests%20%28dbg%29%281%29/builds/45040
https://build.chromium.org/p/chromium.win/builders/XP%20Tests%20%281%29/builds/42690

Original issue's description:
> Implement webview.captureVisibleRegion()
>
> This CL implements  webview.captureVisibleRegion(), an extension/apps
> API to allow WebView users to capture screenshots of the contents
> displayed in a WebView. The surfaces contents capture has been plumbed
> via RenderWidgetHostViewChildFrame so this implementation should not
> require changes when WebView switches to using OOPIF.
>
> As part of the implementation, there are two notable refactors:
>
> 1) CaptureWebContentsFunction has been refactored into
> WebContentsCaptureClient to remove the extensions::AsyncExtensionFunction
> dependence so that this code can be used by both tabs.captureVisibleTab
> and webview.captureVisibleRegion, and
>
> 2) common code from DelegatedFrameHost has ben moved to
> content/browser/compositor/surface_utils.* in order to avoid duplication
> as both DelegatedFrameHost and RenderWidgetHostViewChildFrame now
> use the code.
