Move the QEMU hardware definition of the Windows 11 VM into
qemu/windows11.ini and qemu/windows11-amd64.ini, loaded with -readconfig
like the Linux launchers. The network stays in the launcher because a
config file section cannot hold two hostfwd entries. Add --rdp-port and
--ssh-port, which override the WIN11_VM_*_PORT environment variables.
WIN11_VM_MEMORY and WIN11_VM_CPUS are replaced by the config file.
