E0194 Bonus Formatting

[leikahing]

This ticket covers the bonus portion of #35280 as part of #35233.

It takes the original error message updates and expands it to:

error[E0194]: type parameter `T` shadows another type parameter of the same name
  --> src/test/compile-fail/E0194.rs:13:5
   |
11 | trait Foo<T> {
   |           - first `T` declared here
12 |     fn do_something(&self) -> T;
13 |     fn do_something_else<T: Clone>(&self, bar: T); //~ ERROR E0194
   |                          ^ shadows another type parameter

I made this ticket in order to separate the improvement from the original issue.

I have a fix ready for this/for review but I'm waiting for PR #36056 to be merged into master before I make another PR.
