Auto merge of #67596 - Mark-Simulacrum:tidy-silence-rustfmt, r=Centril

(Mostly) finish formatting the repository

Silences tidy line length warnings on rustfmt-controlled files.

This leaves two things out of formatting: CloudABI (mostly because it's not really ours to control, it's upstream code that's mostly generated), and tests. The latter is a hard problem and maybe not one to worry too much about, we rarely edit old tests and reformatting them as we go if possible isn't too bad (they're generally small).
