Make build-windows-base.sh self-contained and produce a clean base image

The script no longer needs the parent repository or SSH: it builds an answer
ISO from windows11/seed/Autounattend.xml, installs Windows from the ISO in
QEMU (hardware in windows11/qemu uses only devices with inbox Windows
drivers), and the answer file generalizes the image with sysprep at the end.

The base holds only Windows: no account (the built-in Administrator is
disabled), no SSH, no settings, no VirtIO drivers, no machine identity and no
cached answer files. VMs are configured on first boot from an Unattend.xml on
an attached CD-ROM. Add --window and --from-img; press a key at the ISO boot
prompt with the z key, which neither UEFI nor Windows Setup ignores or acts on.
