Distinguishing suggestions from global scope from local suggestions

Code
For the example ts file:

class FooClass {
    toString(): void {
        |
    }
}

Trigger suggestions at the | inside the toString method

Problem
We get back two completions from completionInfo:

     {
            "name": "toString",
            "kind": "function",
            "kindModifiers": "declare",
            "sortText": "0"
        },
        {
            "name": "toString",
            "kind": "method",
            "kindModifiers": "",
            "sortText": "0",
            "insertText": "this.toString"
        },

However when we then make the completionEntryDetails request, we can only pass the identifier name: "toString". This makes it unclear which completion entry we are actually requesting completion details for.

Proposal
completionEntryDetails already has a source field that is used to identify when a suggestion is an auto import. I believe that this field could also be used for global symbols, such as when a symbol name comes from a global lib.d.ts file. In this case, the first toString suggestion comes from a global in dom.d.ts

Usa el ejemplo de FooClass para reproducir las finalizaciones duplicadas de toString que devuelve completionInfo. Lee cómo completionEntryDetails usa actualmente source para las importaciones automáticas y, después, evalúa el caso propuesto de símbolos globales de dom.d.ts; estará terminado cuando los consumidores puedan distinguir las entradas y solicitar los detalles correspondientes.
