Add refactoring action to annotate a variable or a function signature component with its inferred type

Hi, I'm using latest stable VSCode / latest nightly TS and I'm not sure if codefixes and refactorings have been implemented there yet, in any case, having a refactoring option to take any variable which receives an implicit inferred type, say, through a function call:

function test(): number[] {
  // ...
}

let x = test(); 

And being able to right-click x and invoke an action like Annotate with inferred type (or Extract inferred type), such that the resulting statement would look like:

let x: number[] = test();

could be very useful!

Comienza con el comportamiento de corrección de código y refactorización de TypeScript utilizado por VSCode, reproduciendo el ejemplo con la versión nightly más reciente de TypeScript. Define cómo debe manejar la acción los tipos de variables inferidos y los componentes de las firmas de función, y verifica después que produzca anotaciones como let x: number[] = test();.
