kernel: thread: make offload_sem visible for releasing it outside

Browse source 
In order to release irq_offload semaphore outside kernel/thread.c, we
make it visible by modifying it non-static under ztest. This would be
needed such as when call irq_offload() to enter interrupt context and
a fatal error happened, then you have to release it in your fatal
handler, or the irq_offload will still be locked and no longer be
using again.
