include: import Xen public headers to hw/xen/interface
There's already a partial set here; update them and pull in a more
complete set.
To start with, define __XEN_TOOLS__ in hw/xen/xen.h to ensure that any
internal definitions needed by Xen toolstack libraries are present
regardless of the order in which the headers are included. A reckoning
will come later, once we make the PV backends work in emulation and
untangle the headers for Xen-native vs. generic parts.

[dwmw2: Update to Xen public headers from 4.16.2 release, add some in io/,
define __XEN_TOOLS__ in hw/xen/xen.h, move to hw/xen/interface/]
