1. Print token::Interpolated with token stream pretty printing. …

   Instead of using AST pretty printing.
   
   This is a step towards removing `token::Interpolated`, which will
   eventually (in rust-lang#124141) be replaced with a token stream within invisible
   delimiters.
   
   This changes (improves) the output of the `stringify!` macro in some
   cases. This is allowed. As the `stringify!` docs say: "Note that the
   expanded results of the input tokens may change in the future. You
   should be careful if you rely on the output."
   
   Test changes:
   
   - tests/ui/macros/stringify.rs: this used to test both token stream
     pretty printing and AST pretty printing via different ways of invoking
     of `stringify!` (i.e. `$expr` vs `$tt`). But those two different
     invocations now give the same result, which is a nice consistency
     improvement. This removes the need for all the `c2*` macros. The AST
     pretty printer now has more thorough testing thanks to rust-lang#125236.
   
   - tests/ui/proc-macro/*: minor improvements where small differences
     between `INPUT (DISPLAY)` output and `DEEP-RE-COLLECTED (DISPLAY)`
     output disappear.
