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.

Store idents for `DefPathData` into crate metadata Previously, we threw away the `Span` associated with a definition's identifier when we encoded crate metadata, causing us to lose location and hygiene information. We now store the identifier's `Span` in the crate metadata. When we decode items from the metadata, we combine the name and span back into an `Ident`. This improves the output of several tests, which previously had messages suppressed due to dummy spans. This is a prerequisite for #68686, since throwing away a `Span` means that we lose hygiene information.

Track all predicates in errors, not just trait obligations Surface associated type projection bounds that could not be fulfilled in E0599 errors. Always present the list of unfulfilled trait bounds, regardless of whether we're pointing at the ADT or trait that didn't satisfy it.
