Add ARM64 ISO build for Apple Silicon / UTM

- iso/docker/Dockerfile.arm64: Arch Linux ARM base (menci/archlinuxarm:aarch64)
- iso/docker/entrypoint-arm64.sh: ARM64 archiso profile — linux-aarch64
  kernel, EFI-only boot (no syslinux), aarch64 squashfs path, spice-vdagent
  for UTM clipboard, VirtIO GPU modesetting config
- build-iso-arm64.sh: docker buildx --platform linux/arm64 wrapper;
  runs natively on Apple Silicon, no QEMU emulation needed
