KVM: arm64: Enable ring-based dirty memory tracking
Enable ring-based dirty memory tracking on ARM64:
- Enable CONFIG_HAVE_KVM_DIRTY_RING_ACQ_REL.
- Enable CONFIG_NEED_KVM_DIRTY_RING_WITH_BITMAP.
- Set KVM_DIRTY_LOG_PAGE_OFFSET for the ring buffer's physical page
offset.
- Add ARM64 specific kvm_arch_allow_write_without_running_vcpu() to
keep the site of saving vgic/its tables out of the no-running-vcpu
radar.
