Detect multiple crate versions on method not found
When a type comes indirectly from one crate version but the imported trait comes from a separate crate version, the called method won't be found. We now show additional context:
```
error[E0599]: no method named `foo` found for struct `dep_2_reexport::Type` in the current scope
--> multiple-dep-versions.rs:8:10
|
8 | Type.foo();
| ^^^ method not found in `Type`
|
note: there are multiple different versions of crate `dependency` in the dependency graph
--> multiple-dep-versions.rs:4:32
|
4 | use dependency::{do_something, Trait};
| ^^^^^ `dependency` imported here doesn't correspond to the right crate version
|
::: ~/rust/build/x86_64-unknown-linux-gnu/test/run-make/crate-loading/rmake_out/multiple-dep-versions-1.rs:4:1
|
4 | pub trait Trait {
| --------------- this is the trait that was imported
|
::: ~/rust/build/x86_64-unknown-linux-gnu/test/run-make/crate-loading/rmake_out/multiple-dep-versions-2.rs:4:1
|
4 | pub trait Trait {
| --------------- this is the trait that is needed
5 | fn foo(&self);
| --- the method is available for `dep_2_reexport::Type` here
```
Fix #128569, fix #110926, fix #109161, fix #81659, fix #51458, fix #32611. Follow up to #124944.
