Add HAP to xen hypervisor capabilities

xen-unstable c/s 16931 introduced a per-domain setting for hvm
guests to enable/disable hardware assisted paging.  If disabled,
software techniques such as shadow page tables are used.  If enabled,
and the feature exists in underlying hardware, hardware support for
paging is used.

Xen does not provide a mechanism to discover the HAP capability, so
we advertise its availability for hvm guests on Xen >= 3.3.
