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

The Xen tools and crash dump analysis tools might not support
pv-domains with more than 512 GB of RAM. This option controls the

It is always possible to change the default via specifying the
