xen: Kconfig: nest Xen guest options
Moving XEN_512GB allows it to nest under XEN_PV. That also allows
XEN_PVH to nest under XEN as a sibling to XEN_PV and XEN_PVHVM giving:
[*] Xen guest support
[*] Xen PV guest support
[*] Limit Xen pv-domain memory to 512GB
[*] Xen PV Dom0 support
[*] Xen PVHVM guest support
[*] Xen PVH guest support
