[Master] fix16017 Remove redeclare of promise from lib.es2016.iterable.d.ts

Fix #16017

[rbuckton]

By removing this, you can no longer take an Iterable for Promise.all or Promise.race. Consider:

function* g() {
  yield Promise.resolve(1);
  yield Promise.resolve(2);
}
Promise.all(g()).then(results => {
});

We either need to structure the files in such a way as to prevent this, or customize the ordering of lib files when we bind to enforce the correct order.
