mod_http_oauth2: Validate consistency of response and grant types
Ensure that these correlated fields make sense per RFC 7591 ยง 2.1, even
though we currently only check the response type during authorization.
This could probably all be deleted if (when!) we remove the implicit
grant, since then these things don't make any sense anymore.
