hw/xen: Extract 'xen_igd.h' from 'xen_pt.h'

Browse Source 
"hw/xen/xen_pt.h" requires "hw/xen/xen_native.h" which is target
specific. It also declares IGD methods, which are not target
specific.

Target-agnostic code can use IGD methods. To allow that, extract
these methos into a new "hw/xen/xen_igd.h" header.
