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.

Replace qemu/<guest>-<arch>.ini with qemu/<guest>-<os>-<arch>.ini, where os is
linux or darwin, the name platform.system() reports. The accelerators move out
of the shared <guest>.ini into these files (KVM on Linux, HVF on macOS, TCG as
the fallback). The launchers pick the file from the host system and
architecture, and reject amd64 guests on macOS hosts, so no darwin-amd64 files
exist.
