Use windows_arm64_url on ARM64 and windows_x64_url otherwise, instead of
the generic windows_url.

cocoa does not scale the guest by default, so the 1024x768 ramfb screen of the
Windows installer looks tiny on a Retina display. zoom-to-fit stretches it to
the window, as UTM does.

With the HVF in-kernel GICv3, QEMU's usb-storage races on the status packet
and Windows Setup stalls 10 s after every burst of reads when installing from
the ISO (utmapp/UTM#7970). Use the emulated interrupt controller until
upstream QEMU gets the fix from the UTM fork. Record the investigation in
windows11-arm64-install-speed.md.

Replace ramfb with virtio-gpu-pci at 2048x1280 and install the viogpudo
driver from the VirtIO ISO. ramfb has a fixed mode, and keeping both
adapters left Windows with a second, fixed-mode monitor.
Windows Setup and the base image have no viogpudo driver, so on the
launch that creates the system disk the launcher also adds a ramfb ahead
of the config files. The display window shows the first GPU.

On Arm64 Windows the VirtIO guest tools installer is an x86 program and the
VirtIO ISO has no Arm64 package for it, so the first-logon script failed there
and the guest had no network (no NetKVM driver). Install the Arm64 NetKVM,
vioserial, Balloon, viorng and vioinput drivers from their folders on the ISO
with pnputil instead.
The OpenSSH Server capability is downloaded through Windows Update, which can
take very long and blocked the rest of the script. Move it, with the
administrator authorized key, into 05-Install-OpenSSH-Admin.bat, which the
script copies to the Installers folder on the desktop to run by hand.
Update the vm-images submodule to the build script that runs on Debian.

Reading the installation files through QEMU's emulated USB CD-ROM runs at a
few MB/s on macOS. --install-from-img FILE (or WIN11_VM_INSTALL_IMG) attaches
an installation disk image built by vm-images/build-windows-install-disk.sh as
an NVMe disk instead, which is read about 15 times faster. The image is
attached with snapshot=on because NVMe cannot report write protection and
Windows fails on a read-only volume.
Add windows11-arm64-install-speed.md with the analysis and measurements.

Pick qemu-system-aarch64, the AArch64 UEFI firmware and a per-architecture
QEMU config (NVMe disk, virtio-net, ramfb, USB installation media) on arm64,
render the answer file for the target architecture, and move the q35-only
disk and NIC devices out of the shared config. Update vm-images to match
arm64 Windows ISO names.

A [netdev] in a -readconfig file does not stop QEMU from adding its
default NIC, so the guests had a second user-mode network without the
SSH port forward. Both NICs got 10.0.2.15 over DHCP, and SSH only worked
on boots where the forwarded NIC won the race for the default route.
Removing the default NIC shifts the other PCI devices down one slot, so
existing VMs may need their UEFI variable store reset to boot again.
