`OSError` when creating a `multiprocessing.Queue` with `maxsize > 32767`

Bug report

Bug description:

While exploring multiprocessing.Queue, I encountered an exception which was confusing and I couldn't reconcile from Googling. Briefly, it seems that the Queue object allows providing a maxsize which exceeds from .synchronize import SEM_VALUE_MAX. If that occurs, the exception below is raised.

I suspect but haven't confirmed that this issue exists in main as the maxsize does not carry an upper bound.

If this is acknowledged as a bug, or at least a source of improvement for the user experience, I would be happy to provide a pull request that (1) sets an upper bound as SEM_VALUE_MAX and (2) provides a Warning that the upper bound was exceeded.

            print(f"writer placed {i}", flush=True)
        self.q.put(None)

    def reader(self):
        while True:
            i = self.q.get()

Comienza con el gh-119542 enlazado y, después, inspecciona Lib/multiprocessing/queues.py y Lib/multiprocessing/synchronize.py en torno a la inicialización de Queue y SEM_VALUE_MAX. Reproduce el comportamiento con queue-test.py usando los valores de maxsize 32767 y 32768; done debería solucionar el fallo de argumento no válido para valores superiores al límite de semaphore compatible.
