Add machine applicable suggestion for `bool_assert_comparison`
Fixes#7598
Also closes#8118, it had already been fixed by an earlier change but I've added a test for it
changelog: [`bool_assert_comparison`] The suggestion is now machine applicable
Use UnordMap and UnordSet for id collections (DefIdMap, LocalDefIdMap, etc)
This PR changes the `rustc_data_structures::define_id_collections!` macro to use `UnordMap` and `UnordSet` instead of `FxHashMap` and `FxHashSet`. This should account for a large portion of hash-maps being used in places where they can cause trouble.
The changes required are moderate but non-zero:
- In some places the collections are extracted into sorted vecs.
- There are a few instances where for-loops have been changed to extends.
~~Let's see what the performance impact is. With a bit more refactoring, we might be able to get rid of some of the additional sorting -- but the change set is already big enough. Unless there's a performance impact, I'd like to do further changes in subsequent PRs.~~
Performance does not seem to be negatively affected ([perf-run here](https://github.com/rust-lang/rust/pull/106977#issuecomment-1396776699)).

Fix spelling inconsistence of `mdBook`
I was reading both [mdBook Documentation](https://rust-lang.github.io/mdBook/) and [The Clippy Book](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/book.html#the-clippy-book) and felt that it's easier to read to unify the notation of `mdBook`.

[needless_return]: Remove all semicolons on suggestion
Closes#10182
Multiple semicolons currently breaks autofix for `needless_return` suggestions. Any semicolons left after removing return means that the return type will always be `()`, and thus fail to compile.
This PR allows `needless_return` to remove multiple semicolons.
The change won't cover the case where there is multiple line yet.
i.e.
```rust
fn needless_return() -> bool {
return true;
;;
}
```

`cast_possible_truncation` Suggest TryFrom when truncation possible
This fixes the last issues from https://github.com/rust-lang/rust-clippy/pull/9664 as the author seems to be inactive. The PR author was sadly kept during the rebase, due to the conflict resolution.
IDK if it's worth it do to a full review, I only added the last commit, everything else remained the same, besides a rebase.

Add missing arguments to `new_lint` example of `cargo` lints
changelog: Add missing arguments to `new_lint` code example.
From the surrounding text, it seems like this code example is missing the arguments to create a new `cargo` lint.
Render missing generics suggestion verbosely
It's a bit easier to read like this, especially ones that are appending new generics onto an existing list, like ": `, T`" which render somewhat poorly inline.
Also don't suggest `dyn` as a type parameter to add, even if technically that's valid in edition 2015.
