Henrik Hørlück Berg dceefcdaba Add an appenln method to output_stream_t
This is an alternative to the very common pattern of

```rust
streams.err.append(output);
streams.err.append1('\n');
```

Which has negative performance implications, see https://github.com/fish-shell/fish-shell/pull/9229

It takes `Into<WString>` to hopefully avoid allocating anew when the argument is
a WString with leftover capacity
