Fix the problem of the access-denied error when using a 'new
window.ActiveXObject("Microsoft.XMLHTTP")' to access URIs from custom
WebView scheme handler of the Internet Explorer WebView.
The solution here is to implement PARSE_SECURITY_URL and
PARSE_SECURITY_DOMAIN in ParseUrl of the IInternetProtocolInfo interface
of the Internet Explorer Control.
The direct implementation of VirtualProtocol::QueryInterface() instead
of using IMPLEMENT_IUNKNOWN_METHODS works, but is not nice. The better
approach would be probably enhancing ADD_RAW_IID to support multiple
inheritance.
Closes#17893.
