xen: add xen_set_domain_pte()

Add xen_set_domain_pte() to allow setting a pte mapping a page from
another domain.  The common case is to map from DOMID_IO, the pseudo
domain which owns all IO pages, but will also be used in the privcmd
interface to map other domain pages.

[ Impact: new Xen-internal API for cross-domain mappings ]
