Reasons for feature removals are not translatable

[Xiretza]

Code

#![feature(box_syntax)]

fn main() {}

Current output

error[E0557]: feature has been removed
 --> foo.rs:1:12
  |
1 | #![feature(box_syntax)]
  |            ^^^^^^^^^^ feature has been removed
  |
  = note: replaced with `#[rustc_box]`

error: aborting due to 1 previous error

For more information about this error, try `rustc --explain E0557`.

Desired output

The note ("replaced with #[rustc_box]") should be translatable, rather than hard-coded in compiler/rustc_feature/src/removed.rs.

Rationale and extra context

The reason field in RemovedFeature cannot simply be replaced with a DiagMessage because rustc_features cannot depend on rustc_errors (cyclic dependency). I don't know how to solve this.
