Added recordFeedback API to GlicBrowserHostJournal

The purpose of this API is to record a listnr feedback with a snapshot
of the journal included. This API is planned to be triggered whenever a
response is rated and will include the reason (if applicable).

Note: The now duplicated `GlicWebClientHandler::SendResponseFeedback` is
kept until the new API is called from the client. This is mainly because
the feature is being actively tested.
