Provide a runtime flag to run-webkit-tests that shows the test view

[Brent Fulgham]

I find it helpful when debugging tests to be able to see the WebView as the test runs. We should provide a runtime flag so that instead of rendering off screen we can display the view.

This should be available for:
1. DumpRenderTree
2. WebKitTestRunner
3. TestWebKitAPI

[Brent Fulgham]

Skipping TestWebKitAPI for now, since it doesn't process its own arguments (it's all driven by the Google test infrastructure.

Since this is only needed for debugging while creating tests, we will invoke it via the "--additional-drt-flag" option:

--additional-drt-flag="--show-webview"

Why this bit? It's different from how handleOptionRemoteLayerTree works.

I don't get why these have to go to the injected bundle. We create the view in the UI process.

OK -- I fixed it to be consistent with "--remote-layer-tree".

I was just blindly following the "timeout" option. We don't need this for the InjectedBundle. I'll remove it.
