RTEMS osal queue mixed sizes

[thesamprice]

Describe the bug
Im using queues to send variable length messages.
RTEMS queue get returns an error if the message queue returned size is not the max buffer size.
https://github.com/nasa/osal/blob/main/src/os/rtems/src/os-impl-queues.c#L235

This doesn't match the posix implementation.
https://github.com/nasa/osal/blob/main/src/os/posix/src/os-impl-queues.c#L194

The above logic in shared/src/osapi-queue.c uses OS_QUEUE_INVALID_SIZE If the queue size is greater than the buffer provided.

        if (size < queue->max_size)
        {
            /*
            ** The buffer that the user is passing in is potentially too small
            */
            *size_copied = 0;
            return_code  = OS_QUEUE_INVALID_SIZE;
        }

To Reproduce
Steps to reproduce the behavior:
Visual inspection.

Expected behavior
Follow the posix logic.
