Error bridged to NSError's `localizedDescription` doesn't use the `CustomStringConvertible`

[weissi]

This is very similar to #50193

import Foundation
struct MyError: Error, CustomStringConvertible { let description = "this is the right description" }
print((MyError() as NSError).localizedDescription)

leads to

$ pbpaste | swift -
The operation couldn’t be completed. (main.MyError error 1.)

so whatever you do, it'll show (TheErrorType error 1.).

Just want to mention you can still conform your error type to Foundation's LocalizedError and provide a errorDescription. Then it'll show whatever is in errorDescription instead of (TheErrorType error 1.).
