gh-123089: Make weakref.WeakSet safe against concurrent mutations while it is being iterated  (#123279)

* Make `weakref.WeakSet` safe against concurrent mutations while it is being iterated.

`_IterationGuard` is no longer used for `WeakSet`, it now relies on copying the underlying set which is an atomic operation while iterating so that it can be modified by other threads.
