hw/intc/arm_gicv3: Extract gicv3_set_gicv3state from arm_gicv3_cpuif.c

gicv3_set_gicv3state() is used by arm_gicv3_common.c in
arm_gicv3_common_realize(). Since we want to restrict
arm_gicv3_cpuif.c to TCG, extract gicv3_set_gicv3state()
to a new file. Add this file to the meson 'specific'
source set, since it needs access to "cpu.h".
