[JavaScript/TypeScript Language Hints] Hide default `Function` properties/methods until manually typed just like in Rust.

Right now if I create a class with static methods/properties or via namespace, it's very hard to distinguish between default and custom ones visually.

I propose to hide those default methods, they are not useful to know for beginners, while for experienced ones, it's noisy. Leaving only defined in classes/namespaces.
I'm looking from Rust lang analyzer extension perspective, which does exactly that, and I feel like it's much more convenient, especially if there will be more properties/methods in future.
If the property is fully typed correctly, e.g. Test.call, the hint will appear just like typing Test.constructor, it's not appearing, but when typed - the hint appears with Function.

This can be an option to enable/disable.

Comienza reproduciendo los ejemplos de autocompletado de clases y namespaces descritos en la issue y, después, compara las sugerencias de lenguaje actuales de TypeScript con el comportamiento de Rust analyzer. Se considera terminado cuando los miembros predeterminados de Function están ocultos hasta que se escriba su tipo explícitamente, mientras que los miembros personalizados siguen visibles y se contempla una opción para activar/desactivar esta función.
