[11.x] add function to get faked events (laravel#50905)

* add function to get faked events

this function will return an array of all Events that have been faked.

this can be helpful when originally writing the tests to get a grasp of which events you may need to intercept.

both the `QueueFake` and `NotificationFake` have similar methods to let you see what has been intercepted by the fake.
