Improve missing_abi lint

This is for the migration lint for rust-lang/rfcs#3722

It is not yet marked as an edition migration lint, because `Edition2027` doesn't exist yet.

The lint now includes a machine applicable suggestion:

```
warning: extern declarations without an explicit ABI are deprecated
 --> src/main.rs:3:1
  |
3 | extern fn a() {}
  | ^^^^^^ help: explicitly specify the C ABI: `extern "C"`
  |
```
