Disable Surface Synchronization for DualBrowserStorySet's WebView

DualBrowserStorySet uses non-standard set-up to create its webview,
missing the previous option customization added to PerfBenchmark's
CustomizeBrowserOptions. While this should probably be unified,
copying the relevant options over for now to un-break the dual browser
case.

Also disables VizDisplayCompositor, as this is a related unsupported
feature, and although things happen to work now, we don't want to rely
on that.
