Connect to ScriptMessageWithReplyReceived signal.

This signal is emitted when JavaScript in a web view calls

window.webkit.messageHandlers.<name>.postMessage(), after registering <name> using

[webkit.user_content_manager.UserContentManager.registerScriptMessageHandlerWithReply]

The given reply can be used to send a return value with [webkit.script_message_reply.ScriptMessageReply.returnValue] or an error message with [webkit.script_message_reply.ScriptMessageReply.returnErrorMessage]. If none of them are called, an automatic reply with an undefined value will be sent.

It is possible to handle the reply asynchronously, by simply calling [gobject.object.ObjectWrap.ref_] on the reply and returning true.
