Move the Debian launcher's QEMU arguments into qemu/debian13.ini, which
the launcher renders with the per-run file paths and passes to QEMU with
-readconfig, followed by qemu/debian13-<arch>.ini for the machine type
and arm64-only devices. Memory, CPU count, SSH port and accelerator are
now set in the config files, replacing VM_MEMORY, VM_CPUS and
VM_SSH_PORT; VM_QEMU_CONFIG selects a different shared config file.
