Rollup merge of #129344 - compiler-errors:less-option-unit-diagnostics, r=jieyouxu
Use `bool` in favor of `Option<()>` for diagnostics

We originally only supported `Option<()>` for optional notes/labels, but we now support `bool`. Let's use that, since it usually leads to more readable code.

I'm not removing the support from the derive macro, though I guess we could error on it... 🤔
