libcef: Update due to underlying chromium changes.

- Canvas classes moved from gfx namespace to skia namespace.
- Include files moved from WebKit/port to third_party/WebKit.
- Add IsMediaPlayerAvailable() webkit_glue function.
- WebWidgetDelegate::GetContainingWindow() changed to WebWidgetDelegate::GetContainingView().
- Changed HCURSOR to WebCursor and HWND to gfx::NativeWindow.
- WebPluginInfo 'file' member changed to 'path'.
- Use base::LazyInstance for static object in BrowserPluginInstance (should be done at some point for BrowserPluginLib and BrowserPluginList as well).
- BrowserPluginStream::Open() adds additional 'request_is_seekable' parameter.
- Add PLUGIN_QUIRK_PATCH_SETCURSOR support to BrowserWebPluginDelegateImpl.
