KVM: arm64: gic-v5: Add VGICv5 IST save/restore UAPI
Introduce KVM_DEV_ARM_VGIC_GRP_IST as the VGICv5 device attribute
group used to transfer SPI and LPI IST state between KVM and userspace
during migration.
The group uses struct kvm_vgic_v5_ist as a descriptor for the
userspace-owned SPI and LPI IST buffers. Each buffer contains the
architected 32-bit ISTE state for the corresponding interrupt number
space, while the host IST layout remains private to KVM.
The descriptor is architecture-specific, as it is only the payload of
an ARM VGIC device attribute.
