pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not.

error[E0277]: the trait bound `Foo: main::a::Bar` is not satisfied

Add version mismatch help message for unimplemented trait Issue #22750 The error reporting for E0277 (the trait `X` is not implemented for `Foo`) now checks whether `Foo` implements a trait with the same path as `X`, which probably means that the programmer wanted to actually use only one version of the trait `X` instead of the two.
