WKUserScriptCreateFromSource() cannot specify parameters for full WebCore::UserScript and the feature is limited. Because WKPageGroup is deprecated on https://bugs.webkit.org/show_bug.cgi?id=259324, we cannot achieve same thing we could do with WKPageGroupAddUserScript because of the lack of above creation API.
