Diagnostic::sub is only ever used directly; it doesn't need to be
included in the builder.

Remove (lots of) dead code

Builds on
- [ ] rust-lang#83161
- [x] rust-lang#83230
- [x] rust-lang#83197.

Found with https://github.com/est31/warnalyzer.
See rust-lang#77739 for a similar change in the past.

Dubious changes:
- Maybe some of the dead code in rustc_data_structures should be kept, in case someone wants to use it in the future?

TODO:
- [ ] check if any of the comments on the deleted code should be kept.
- [x] update the compiler documentation; right now it fails to build
- [x] finish moving `cfg(test)` changes into rust-lang#83197
