Message:

False-positive over-release of WebView in destroyWebViewAndOffscreenWindow() in DumpRenderTree.mm
<​https://webkit.org/b/158716>

Reviewed by Andy Estes.

• DumpRenderTree/mac/DumpRenderTree.mm:

(destroyWebViewAndOffscreenWindow): Change this function to take
a WebView, and assert that it's the same as [mainFrame webView].
(dumpRenderTree): Pass 'webView' into
destroyWebViewAndOffscreenWindow().

• DumpRenderTree/mac/DumpRenderTreeMac.h:

(createWebViewAndOffscreenWindow): Add NS_RETURNS_RETAINED since
this function returns a +1 WebView. Declare this method only for
Objective-C[++] source.
