unused-lifetimes: don't warn about lifetimes originating from expanded code
previously, we would warn like this:
````
warning: lifetime parameter `'s` never used
--> /tmp/unusedlif/code.rs:6:62
|
5 | #[derive(Clone)]
| - help: elide the unused lifetime
6 | struct ShimMethod4<T: Trait2 + 'static>(pub &'static dyn for<'s> Fn(&'s mut T::As));
| ^^
|
= note: requested on the command line with `-W unused-lifetimes`
````
Fixes #104432
