[issue41339] make queue.Queue objects iterable

[Alan Iwi]

New submission from Alan Iwi <alan.iwi at stfc.ac.uk>:

It is possible to make `queue.Queue` and `queue.SimpleQueue` objects iterable by adding simple `__iter__` and `__next__` methods.  This is to suggest adding these methods to the existing `Queue` and `SimpleQueue` so that they are iterable by default.

```
class Fifo(SimpleQueue):

    def __iter__(self):
        return self

    def __next__(self):
        if not self.empty():
            return self.get()
        raise StopIteration
```
