irq_work: Introduce arch_irq_work_has_interrupt()
commit c5c38ef3d70377dc504a6a3f611a3ec814bc757b upstream.
The nohz full code needs irq work to trigger its own interrupt so that
the subsystem can work even when the tick is stopped.
Lets introduce arch_irq_work_has_interrupt() that archs can override to
tell about their support for this ability.
