This is take two of #70976. This iteration of the patch makes sure that custom diagnostics without any warning group don't get promoted by `-Werror` or `-Wfatal-errors`. This implements parts of the extension proposed in https://discourse.llvm.org/t/exposing-the-diagnostic-engine-to-c/73092/7. Specifically, this makes it possible to specify a diagnostic group in an optional third argument.
