xen: condense everything onto xen_set_pte

xen_set_pte_at and xen_clear_pte are essentially identical to
xen_set_pte, so just make them all common.

When batched set_pte and pte_clear are the same, but the unbatch operation
must be different: they need to update the two halves of the pte in
different order.
