Improve generated overloads

The initial batch of bindings was generated. Some methods have generated overloads.
We should try and improve these manually.
Either via:

• Renaming to hold a more suitable underscore suffix. (See addEventListener as example)
• Remove some of these overloads if they don't make sense. (Like setTimeout taking a string as argument).

Inizia dai file generati elencati sotto src/, usando Global.res e DOMAPI/Element.res come esempi iniziali. Confronta i riferimenti API di addEventListener e setTimeout, quindi esamina ogni overload selezionato per individuare un suffisso appropriato o rimuoverlo; il lavoro è concluso quando le decisioni della checklist sono applicate in modo coerente a tutti i bindings interessati.
