Instead just use `pprust::path_to_string(..)` where needed. This has two benefits: a) The AST definition is now independent of printing it. (Therefore we get closer to extracting a data-crate.) b) Debugging should be easier as program flow is clearer.

Historically I've looked at doing this but didn't see it as immediately actionable. Seems like pprust is still just as coupled with this commit. But I don't mind it, I guess, since it should make further decoupling easier (since you can handle each case separately, vs. an unknown number of cases through a Display/Debug impl). |

(iirc there were rather few dependencies on pprust left in libsyntax after #65324 so in a larger context this should bring us closer to that goal.) |

@bors r+ Changes look correct to me, and it seems to be passing CI. Some of the debug output is probably technically worse now but not in a way that seems immediately bad to me so we can probably leave it be for the time being. |

Remove implicit dependencies on syntax::pprust Part of rust-lang#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. r? @estebank

Part of #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.
