[PATCH v4 10/14] xen/asm-generic: introduce stub header monitor.h

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

The header is shared between several archs so it is
moved to asm-generic.

Signed-off-by: Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>
Acked-by: Jan Beulich <jbeulich@xxxxxxxx>.
---
Changes in V4:
 - Removed the double blank line.
 - Added Acked-by: Jan Beulich <jbeulich@xxxxxxxx>.
 - Update the commit message
---
Changes in V3:
 - Use forward-declaration of struct domain instead of " #include <xen/sched.h> 
".
 - Add ' include <xen/errno.h> '
 - Drop PPC's monitor.h.
---
Changes in V2:
        - remove inclusion of "+#include <public/domctl.h>"
        - add "struct xen_domctl_monitor_op;"
        - remove one of SPDX tags.
