trim paths in `default_trait_access`/`clone_on_copy` suggestions
This should help making the suggestions more palatable. Similar to #10153.

changelog: trim paths in [`default_trait_access`]/[`clone_on_copy`] suggestions
Make the iter_kv_map lint handle ref/mut annotations.
For the degenerate (`map(|(k, _)| k)`/`map(|(_, v)| v)`) cases a mut annotation is superfluous and a ref annotation won't compile, so no additional handling is required. For cases where the `map` call must be preserved ref/mut annotations should also be presereved so that the map body continues to work as expected.
*Please write a short comment explaining your change (or "none" for internal only changes)*

I'm on the train and my internet is too bad to download the necessary toolchain, so I have to use CI to find sync fallout.

It's really nice to see a changelog with so many suggestion fixes and improvements. Not much else to say. This should be merged with the coming release on 2022-12-15. For the reviewer, please review it and approve it if it looks good. The merge should wait until the release :)

Fix 10021
This PR proposes a fix for #10021.
The problem is similar to the one that `@mikerite` described in #9505. The compiler is generating an empty substitution for a call, even though the type of `Self` seems to be needed for a predicate. In `@mikerite's` case, the call was to [`IntoFuture::into_future`](https://doc.rust-lang.org/std/future/trait.IntoFuture.html#tymethod.into_future). In this case, the call is to [`Try::branch`](https://doc.rust-lang.org/std/ops/trait.Try.html#tymethod.branch).
The proposed fix is to verify that the parameter whose type is changing has an index within the substitution. The strikes me as a reasonable approach, since if the check were to fail, the following code would be a no-op:
4c123a06ba/clippy_lints/src/methods/unnecessary_to_owned.rs (L420-L428)
Like `@mikerite's` original solution, this solution turns ICEs into false negatives.

rustc_ast_lowering: Stop lowering imports into multiple items
Lower them into a single item with multiple resolutions instead.
This also allows to remove additional `NodId`s and `DefId`s related to those additional items.

Sorry for taking so long. There were so many blockers and so little time. This situation should be mitigated with #104007 in the future.
Fix#9771 (`unnecessary_to_owned` false positive)
Fixes#9771
In that issue's example(s), the lint tried to add a `&` to a value, which implicitly changed the type of a field to a reference. The fix is to add the reference to `receiver_ty` (the type of the receiver of the `to_owned`-like method), before passing `receiver_ty` to `can_change_type`. `can_change_type` properly rejects the modified `receiver_ty`.
cc: `@mikerite` just because I think he was the author of `can_change_type`.
