Add related error spans for getter/setters with different types

Now that we support multiple related spans for errors (#10489, #22789, #24548), we'd like to improve an existing error message.

Currently, we provide a diagnostic for a pair of get/set accessor's types not matching:

Code:

let x = {
  get foo() { return 100; }
  set foo(value: string): { }
}

Current error:

'get' and 'set' accessor must have the same type.

We'd like to give a better error message. For example:

Primary span:

A 'get-' and 'set-' accessor must have the same type, but this 'get' accessor has the type '{0}'.

Related span:

The respective 'set' accessor has the type '{0}'.

L’issue ne nomme aucun fichier ni test ; commencez par localiser le diagnostic du vérificateur de types TypeScript pour les types d’accesseurs get/set incompatibles et suivre la gestion de son étendue de diagnostic. C’est terminé lorsque le diagnostic principal signale le type du getter, qu’une étendue associée signale le type du setter et que la couverture vérifie les messages et les étendues affichés.
