Enable media stream layout test with content_shell.

When using content_shell to run media stream layout test, it's needed to use override createMediaPlayer because the media stream is generated by TestMediaStreamClient, not MediaStreamImpl which is used by RenderViewImpl::createMediaPlayer.

This patch is needed by patch in https://bugs.webkit.org/show_bug.cgi?id=113633, and they work together to enable media stream layout test in content_shell.
