Implement diagnostic translation for rustc-errors

This is my first PR to rustc yeah~

I'm going to implement diagnostic translation on rustc-errors crate.

This PR is WIP, the reason of opening this as draft, I want to show my code to prevent the issue caused by misunderstanding and also I have few questions.

Some error messages are processed by `pluralize!` macro which determines to use plural word or not. From now, I make two kinds of keys and combine with enum but I'm not sure is this best method to do it.

Is there any prefered method to do this? => This resolved on conversation on PR.

I'll remain to perform force-push until my first implementation looks good to me
