Rollup merge of #125236 - dtolnay:expandtest, r=nnethercote
Add tests for `-Zunpretty=expanded` ported from stringify's tests This PR adds a new set of tests for the AST pretty-printer. Previously, pretty-printer edge cases were tested by way of `stringify!` in [tests/ui/macros/stringify.rs](https://github.com/rust-lang/rust/blob/1.78.0/tests/ui/macros/stringify.rs), such as the tests added by https://github.com/rust-lang/rust/commit/419b26931b73209bfafdb9938c09e12b9d650613 and https://github.com/rust-lang/rust/commit/527e2eac17c5d3709e4e30e8b72ae33a6e8990b1. Those tests will no longer provide effective coverage of the AST pretty-printer after #124141. `Nonterminal` and `TokenKind::Interpolated` are being removed, and a consequence is that `stringify!` will perform token stream pretty printing, instead of AST pretty printing, in all of the `stringify!` cases including $:expr and all other interpolations. This PR adds 2 new ui tests with `compile-flags: -Zunpretty=expanded`: - **tests/ui/unpretty/expanded-exhaustive.rs** — this test aims for exhaustive coverage of all the variants of `ExprKind`, `ItemKind`, `PatKind`, `StmtKind`, `TyKind`, and `VisibilityKind`. Some parts could use being fleshed out further, but the current state is roughly on par with what exists in the old stringify-based tests. - **tests/ui/unpretty/expanded-interpolation.rs** — this test covers tricky macro metavariable edge cases that require the AST pretty printer to synthesize parentheses in order for the printed code to be valid Rust syntax. r? `@nnethercote`
