Preselect completion list entries based on contextual type

It should be cool if tsserver could provide a new command guesstypes to give the capability to guess parameter types when completion is applied

In other word, I would like to support the same feature that I have done with tern

For instance if you open completion for document and select addEventListener :

When you apply completion, I would like call a tsserver command 'guesstypes' to retrieve variables, functions for each function parameters. Here a screenshot which shows a list of variable with string type for the addEventListener type argument :

Inizia leggendo la gestione delle completion di tsserver e confrontala con la funzionalità tern-guess-types collegata. Definisci l’ambito di un comando guesstypes che restituisca variabili e funzioni contestuali per i parametri di completion, e considera come la selezione di una completion dovrebbe usare quel risultato.
