Fix ceftest failures with BackForwardCache enabled (see issue #2421)
When BackForwardCache is enabled the old RFH tree may be cached instead of being immediately deleted as a result of main frame navigation. If a RFH is cached then delivery of the CefFrameHandler::OnFrameDetached callback will be delayed until the the RFH is ejected from the cache (possibly not occurring until the browser is destroyed). This change in OnFrameDetached timing was causing FrameHandlerTest.OrderSubCrossOrigin* to fail, and the inclusion of cached frames in CefBrowserInfo::GetAllFrames was causing FrameTest.NestedIframesDiffOrigin to fail. BackForwardCache is currently being tested via field trials (see https://crbug.com/1171298) and can be explicitly disabled using the `--disable-back-forward-cache` or `--disable-features=BackForwardCache` command-line flags.
