Simplistic quick-fix for #42710. Add a charset argument. If the data is 8

        * camel-mime-utils.c (header_decode_word): Simplistic quick-fix
        for #42710.  Add a charset argument.  If the data is 8 bit, try to
        decode into the passed in charset (i.e. the message header?), at
        worst, fall back to latin1, similarly to header_decode_text.
        Fixed all callers to pass in a charset if available, or NULL.
