Rollup merge of #65363 - Centril:less-pprust, r=Mark-Simulacrum

Remove implicit dependencies on syntax::pprust

Part of https://github.com/rust-lang/rust/pull/65324.

The main goal here is to facilitate the eventual move of pprust out from libsyntax and because an AST definition typically should not depend on its pretty printer.
