This commit adds few Xen public headers, which are needed for further development of Xen features in Zephyr. Headers were taken from include/public directory of Xen RELEASE-4.15.0 branch, filtered and cleaned up to leave only parts, which are now required. Directory structure were saved (public, public/io, public/hvm), so public headers content can be supplemented if nessesary. Signed-off-by: Dmytro Firsov <dmytro_firsov@epam.com>
