Add a two helper functions for those tasks.

Implmented such a unit test using KUnit. Those unit tests verify that ACPI objects are correctly converted into WMI buffers and that WMI strings are correctly converted into ACPI strings. They also verify that invalid ACPI data (like nested packages) is rejected.

Also update the description of the Kconfig entry to better fit with the other subsystem Kconfig entries.
