[PATCH-for-9.0 v2 19/19] hw/xen: Have most of Xen files become target-agnostic

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Previous commits re-organized the target-specific bits
from Xen files. We can now build the common files once
instead of per-target.

Only 4 files call libxen API (thus its CPPFLAGS):
- xen-hvm-common.c,
- xen_pt.c, xen_pt_graphics.c, xen_pt_msi.c

Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>

Reworked since v1 so dropping David's R-b tag.
