[meld/deprecation-cleanup] filediff: Remove current-diff-changed signal

    filediff: Remove current-diff-changed signal
    
    It was only used within FileDiff, so there's really no point to it. We
    can easily add it back once this signal migration is done if it turns
    out to be useful in some way.
