Add wrapper functions for Xen memory managment hypercall. They can be
used for unprivilaged Zephyr guest initialization and for domain
management, when Zephyr is used as Xen Domain 0.

This commit adds possibility to call hypervisor HVM parameter functions
for specified domain (instead of only DOMID_SELF). It is needed for
configuring domains, that were created from Zephyr control domain.

Add Xen domctl API implementation for Zephyr as control domain.
Previously Zephyr OS was used as unprivileged Xen domain (Domain-U),
but it also can be used as lightweight Xen control domain (Domain-0).
To implement such fuctionality additional Xen interfaces are needed.
One of them is Xen domain controls (domctls) - it allows to create,
configure and manage Xen domains.
Also, used it as a possibility to update files copyright and licenses
identifiers in touched files.

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.

This commit adds interface for evtchn allocation that can be used by
privilaged domain. Domain 0 can specify both dom and remote_dom
parameters for hypercall, where in others domains dom should be always
DOMID_SELF. It is needed for creating pre-defined channels during
domain setup in Zephyr Dom0.

Any project with Kconfig option CONFIG_LEGACY_INCLUDE_PATH set to n
couldn't be built because some files were missing zephyr/ prefix in
includes
Re-run the migrate_includes.py script to fix all legacy include paths

This commit introduces driver for granting access for own grant
table and for mapping/unmapping foreign gref. Grant tables are used
for data exchange between Xen domains via shared memory page(s) (e.g.
for sharing ring buffer with driver data) This functionality is
widely used and needed for implementing PV backend/frontend drivers.

This commit adds new functions, which can be used for Xen event channel
management (allocation, interdomain binding etc.). Such functionality
is needed for Xen PV driver development in Zephyr.

The current implementation for events channel is using an empty
callback for every unbind channel and the interrupt is clearing
every event and calling the callback.
However in a scenario where a domain fires a notification when
another has not yet bind the channel, the event will be missed.
To address this limitation, this commit is keeping track of
missed event channel notification when the empty callback is
used, a function to retrieve and clear the missed event is
introduced.

In order to bring consistency in-tree, migrate all includes within
include directory to the new prefix <zephyr/...>. Note that the
conversion has been scripted, refer to zephyrproject-rtos#45388 for more

Move include paths and add new target_include_directories to support
