hw/intc/arm_gicv3_its: Implement MOVALL

Browse source 
Implement the ITS MOVALL command, which takes all the pending
interrupts on a source redistributor and makes the not-pending on
that source redistributor and pending on a destination redistributor.

This is a GICv3 ITS command which we forgot to implement. (It is
not used by Linux guests.)
