[RFC PATCH 0/3] rust: WMI abstractions

[Gladyshev Ilya <foxido@foxido.dev>]

Overview
========
This patchset was developed some time ago out of pure curiosity
about the R4L project, but I believe it may still be useful, so
I decided to resume and post this work.
The goal of my curiosity is to develop a simple WMI driver in Rust
for unsupported laptop (I have some laying around) or, as a last
resort, submit a rewrite of redmi-wmi as a sample driver -- if that
would be acceptable.

I know that there is an undergoing API change in the WMI subsystem[1],
however it doesn't change the abstracted surface a lot.

This patchset consists of 3 patches:
1. Wrapper around ACPI objects (this may be unneeded after [1])
2. WMI abstractions
3. Sample driver for demonstration purposes only

Why RFC?
========
1. No real users for now
2. I have a feeling that I am doing something very wrong
