In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

This commit adds support of Xen Enlighten page and initial support for
Xen event channels. It is needed for future Xen PV drivers
implementation.
Now enlighten page is mapped to the prepared memory area on
PRE_KERNEL_1 stage. In case of success event channel logic gets
inited and can be used ASAP after Zephyr start. Current implementation
allows to use only pre-defined event channels (PV console/XenBus) and
works only in single CPU mode (without VCPUOP_register_vcpu_info).
Event channel allocation will be implemented in future versions.

This commit adds minimal support of Xen hypervisor console via UART-like
driver. Implementation allows to use poll_in/poll_out char interface for
uart_console.c driver directly to HV console instead of using Xen
virtual PL011 UART. Future implementation will support interrupt driven
interface on Xen event channels, currently it is under development.
Also this commit introduces early console_io Xen interface, which allows
to receive printk/stdout messages quickly after start, but requires Xen,
built with CONFIG_DEBUG option.
