Description
Currently, OrderedSet isn't reversible (i.e. allowed to be passed as an argument to Python's reversed()). This would be natural to support given that OrderedSet is ordered. This should be straightforward to add by adding a __reversed__() method to OrderedSet.

Since Simon asked in the PR comments, I'll state the reason for this feature. It would be useful for resolving #32516, which involves reversing a number of OrderedSet objects.

Yes, I accepted assuming it'd be used in #32516. Sorry I should mention this.
