hw/intc/arm_gicv3: Add irq non-maskable property

Browse source 
A SPI, PPI or SGI interrupt can have non-maskable property. So maintain
non-maskable property in PendingIrq and GICR/GICD. Since add new device
state, it also needs to be migrated, so also save NMI info in
vmstate_gicv3_cpu and vmstate_gicv3.
