Teach structured errors to display short Ty<'_>

[estebank]

Make it so that in every structured error annotated with #[derive(Diagnostic)] that has a field of type Ty<'_>, the printing of that value into a String will look at the thread-local storage TyCtxt in order to shorten to a length appropriate with the terminal width. When this happen, the resulting error will have a note with the file where the full type name was written to.

error[E0618]: expected function, found `((..., ..., ..., ...), ..., ..., ...)``
 --> long.rs:7:5
  |
6 | fn foo(x: D) { //~ `x` has type `(...
  |        - `x` has type `((..., ..., ..., ...), ..., ..., ...)`
7 |     x(); //~ ERROR expected function, found `(...
  |     ^--
  |     |
  |     call expression requires function
  |
  = note: the full name for the type has been written to 'long.long-type-14182675702747116984.txt'
  = note: consider using `--verbose` to print the full type name to the console

Needs rebase due to #135726 which added

impl IntoDiagArg for RustcVersion {
    fn into_diag_arg(self) -> DiagArgValue {
        DiagArgValue::Str(Cow::Owned(self.to_string()))
    }
}
