WMI strings are encoded using UTF16-LE characters, forcing WMI drivers
to manually convert them to/from standard UTF8 strings. Add a two
helper functions for those tasks.

platform/x86: wmi: Move WMI core code into a separate directory2025-11-18T09:18:11+00:00Armin WolfW_Armin@gmx.de2025-11-11T13:11:25+00:00urn:sha1:e2c1b56f3dfa014128e775e898774c0356e3ff05
Move the WMI core code into a separate directory to prepare for
future additions to the WMI driver. Also update the description
of the Kconfig entry to better fit with the other subsystem
Kconfig entries.

platform/x86: wmi: Update WMI driver API documentation2024-10-06T10:48:52+00:00Armin WolfW_Armin@gmx.de2024-10-05T21:38:24+00:00urn:sha1:5984b40f5bcd41bfd08359cdb9c8cb7ca9d3cc60
The WMI driver core now passes the WMI event data to legacy notify
handlers, so WMI devices sharing notification IDs are now being
handled properly.

Add documentation for the WMI subsystem. The documentation describes
both the ACPI WMI interface and the driver API for interacting with
the WMI driver core. The information regarding the ACPI interface
was retrieved from the Ubuntu kernel references and the Windows driver
samples available on GitHub. The documentation is supposed to help
driver developers writing WMI drivers, as many modern machines designed
to run Windows provide an ACPI WMI interface.
