Auto merge of #58140 - eddyb:advent-of-print, r=nikomatsakis
Refactor ppaux out of existence. A long-time coming, this PR reorganizes and rewrites the pretty-printing architecture of rustc, specifically the parts that involve the typesystem (which used to be in `rustc::util::ppaux`). *Note: these commits used to be in #57967 before being split off.* The new API (i.e. the `Printer` and `PrettyPrint` traits) is in `rustc::ty::print`. Design points, roughly: * using associated types in `Printer` to allow building e.g. an AST, not just printing as a side-effect * several overloading points for implementers of `PrettyPrinter`, e.g. how `<...>` is printed * for `fmt::Display` impls, the value to print is lifted to the `ty::tls` `tcx`, and everything after that stays within the `ty::print` API, which requires `'tcx` to match between values and the printer's `tcx`, without going through `fmt::Display` again Most of the behavior is unchanged, except for a few details, which should be clear from the test changes. r? @nikomatsakis Fixes https://github.com/rust-lang/rust/issues/55464
