xen: dom0: update Xen public headers for running Zephyr as Dom0

Xen public headers are added to Zephyr kernel partially, so we need
to update them for new features implementation.

Further implementation of Xen domains configuration and memory
management requires dedicated Xen public headers inside Zephyr kernel.
It will be used for add Zephyr OS Xen Domain-0 funtionalities.

Update existent and add new required public headers from Xen 4.17.0
release.
