fix(#381): add support of stdlib identifier collisions.

[JSMonk]

Summary

Those changes solve the problem with identifiers hidden with TypeScript definitions. For example:

declare interface Any {
  id(a: any): Any;
}

This code snippet is translated into the next one:

external interface Any {
  fun id(a: Any): Any
}

But proposed behaviors is to translate it into:

external interface Any {
  fun id(a: kotlin.Any): Any
}
