qtest/irq: Rework IRQ interception
Change the qtest intercept handler to accept just the individual IRQ being intercepted as opaque. n is still expected to be correctly set as for the original intercepted irq. qemu_intercept_irq_in is updated accordingly. Then covert the qemu_irq_intercept_out call to use qdev intercept version. This stops qtest from having to mess with the raw IRQ pointers (still has to mess with names and counts but a step in the right direction).
