Fix test_configure_logging_custom_handlers test for ARM (#2112)

* Replace usage of `multiprocessing.Queue.qsize` with `multiprocessing.Queue.empty`, in the `_flush_logging_queue` helper method which was used by the `test_configure_logging_custom_handlers`.
* The `multiprocessing.Queue.qsize` method would raise a `NotImplementedError` on some platforms, notably linux/arm64 ref: https://docs.python.org/3.10/library/multiprocessing.html?highlight=queue#multiprocessing.Queue.qsize.
