bors d9d4d39612 Auto merge of #73565 - matthewjasper:core-min-spec, r=nagisa
Use min_specialization in libcore

Getting `TrustedRandomAccess` to work is the main interesting thing here.

- `get_unchecked` is now an unstable, hidden method on `Iterator`
- The contract for `TrustedRandomAccess` is made clearer in documentation
- Fixed a bug where `Debug` would create aliasing references when using the specialized zip impl
- Added tests for the side effects of `next_back` and `nth`.
