gtk: support RGBA end-to-end compositing when using RedirectedXCompositeWindow

Because your patch adds Alpha support to current implementation, it would be good to use "bool supportAlpha" instead of depth.

I don't think we need to use websettings.
It would be better to modify WebKitWebViewBase to decide whether RGBA support is needed.
ex) If parent window of webview uses RGBA, we can use RGBA support.
